Can you make a video on inverter used in tesla model S and also tell how to make one with list of all components ,im planning to power my car on electricity . Please help, i was not able to find its design anywhere on internet!
Sir.....audio visual demonstrations are always the best method of making the making-out, according to my thought. Why our schools-colleges don't arrange mass by Documentations? 😭 Thank You Sir.
3 hours of your videos would replace my whole 4 year highschool education. Its just mind blowing how far IT has come. You sir are doing honorable work here.
School is a bloody scam... 16 years of education and you probably don't have any skills... just a bunch of theories which you probably just crammed to pass exams... useless
I think your over exaggerating slightly or more like your high school education was all about the polo bears melting on account of us people driving cars, halfwit ‘students’ without any common sense!.
I rarely comment but here I have to. I am an engineering student and I have to finish this assessment for next week, part of the assessment is to design an inverter that is connecting a solar pannel to AC loads. I must confess that until now I only had a vague idea of what an inverter is, but with this video I finally have a complete understanding of the working of such a device. Power electronics is clearly not my favorite course but at least you have made it comprehensible, thank you very much.
For an engineering student who doesn’t hardly know much about an inverter, does indeed say something about today’s ‘students’ probably out blocking traffic and glueing themselves to Aeroplanes because we humans are melting the ‘planet’!
@@svwtsvfcbSeems like astragreen has decided you waste your time as an activist student, blocking traffic and other things, because of what you admitted. Astragreen seems to believe university students are mostly leftwing marxist reprobate minds, who've wasted their time becomming brainwashed activist useless eaters, other than educated, driven, members of society who are the next generation engineers, scientists, researchers etc.. Astrogreen is right that the world has lost thousands of youths to the cesspool of the left. But astrogreen is wrong to judge you without real evidence. Judge not, that ye not be judged. The evil of the left is sending America to its death. Reprobate minds cannot see it. It is nearly impossible for them to do so. Plain physics, on the spiritual plane.
@@svwtsvfcbIn a round about way he's condemning higher education systems that put a focus on teaching global warming or simularly gender or racial equity rather than a focus on engineering principles students need to understand what they are working on or with, and the low bar of useful education students recieve. I don't know how far you're into your education, and neither does the previous commentator. But if you're just beginning your degree, then I'd say there's no big sign of a problem yet. But if you're near finishing your degree and you're just comming to understand an inverter, then maybe you should question your school and how messed up it is that people and you spend gobs and gobs of money for useless information that benefits neither the students, nor their future employers, nor their employer's customers, nor socity in general. Instead you're saddled with massive debt and foreigners take your job opportunities because you're not well qualified. That's politely pretty much the intention behind the previous commentator. While I pretty much agree with that generally about the average student, I'm glad you're seeking out information and found this video helpful. And I hope that you focus on education that helps you better satisfy people's needs through your engineering degree. And I hope that putting those skills to use benefits you financially and those who you help, or are helped by your work. 😊
Just one word "Love" your work ! Amazes me what I lost in my Engineering and what I gain here and other videos of yours. Will definitely pursue my Masters after a gap of 15 long years working in IT. Thank you !!

Very good for the basics of an inverter. Personally I used to startup AC variable speed inverters using SCRs as switches. The trick to using SCRs is the ability to turn them off, which requires a reverse bias. The IGBT came along later. The advantage for them is that they can be turned off by removal of the trigger signal. The advent of the IGBT significantly reduced the cost of the inverter and or AC variable speed drive. Note that all inverters wither AC or DC sourced, have a constant voltage DC Buss dependent on the value of the input voltage.. The DC buss voltage results in a constant Peak to Peak voltage. The pulse width modulation as described in this articular is used to vary both the frequency of the output as well as the output RMS (effective) voltage. When used for variable speed when powering an AC motor, constant torgue is maintained by keeping the ratio of the frequency to the RMS voltage constant. For a 460 VAC to 60 hertz system this ratio is 7.67 V/hz. Once the motor rated speed from a constant voltage/frequency system is reached, the motor speed can still be increased by just increasing the frequency with no further increase in voltage. This is called the constant horsepower range. Their is a limit to this as the torque decreases to a point where the motor will no longer run. An inverter and or AC variable speed drive with a 3 phase output has another advantage in that the motor rotational direction can be reversed by just reversing the phase sequence as controlled by the triggering sequence of the IGBTs.
I remember learning this in some electronics courses. The Toyota Prius hybrid had been using LARGE IGBT's for it's 3 phase motor. Napa Auto Parts training side had a fantastic course explaining how it all worked and more that was built into the system. Of course this video answers questions much better than the books I've read, and I thank you for this. If anyone is learning about DC to DC and DC to AC inverters and converters. That Napa course will give a lot of info, but this video is the start! I'm assuming people that see this video understand the basic theory that "When magnetic lines of force cut across a conductor, a voltage is induced in the conductor and current (electrons) can flow." Without this "working theory," we'd never have the great electrical and electronics we have now!
Within one video you covered lots of topics and explained everything in a very simple language - this is what modern books and lecturers can't do Thanks for your work. 've been a proud subscriber of your channel since 2016 Look forward for more engines, electricity and electronics stuff explained
I’m a pilot, just started flying as second in command of a Hawker 400 which has a much more complex electrical system than what I’m used to. So I came here to learn about inverters. Thanks👍🏼
It's funny because honestly, your professor should be giving you this kind of detail. Guys like this are going to put the classic professor out of business
Great video and explanation. One side note: Sometimes it might be difficult to get hold of a 3-phase inverter or an inverter capable of outputting the amount of power required. Therefore, some manufacturers offers inverters that can be connected in parallel to get more 2 or 3 phases instead of one, or in series to get more power (as in more Amps or Watts), or even combined in parallel and series to get perhaps 3-phases at 32 Amps instead of 3-phases at 16 Amps. But please be aware that only some manufacturers offers these solutions, and also that it is usually required that the inverters can communicate through perhaps a CAN network. Another side note: You mention inverters outputting square vawe AC and modified sine AC. Please aware that there are also som inverters which output "pure" AC; ie. with very few or no ripples and a pattern when viewed on an oscilloscape virtually indentical with what you will get from something like a wall socket. Also, some devices like certain electronics might be unstable or even be damaged if used with square vawe or modified sine AC.
Yes, good advice! Also, for any viewers who don't know, there's one more thing to be aware of as the winter approaches and we face the possibility of power outages, like last winter (2021.) - AC generators (standard gasoline generators.) Be careful about what you plug into a standard AC generator. They too produce a "dirty" square wave. Televisions and any other electronic appliances that have multiple circuits with various voltages inside them will not respond well to regular AC generators. They require an Inverter Generator, which produces AC voltage, then converts it to DC voltage, then inverts it to "clean" AC voltage with a smooth sine wave (as shown in this video.)
In building my first electric car, this has been super helpful. I'd like to know more about the current load relationship between source voltage DC into the motor controller vs motor controller output after converted to 3 phase. I can easily get motor specs however I need to spec connections to the battery packs. Most connectors I find are rated at a far lower ampacity than I'm dealing with while utilizing a much larger conductor. 90mm2 vs my 50mm2 that was included with the supplied parts. Thanks again for making these videos very helpful and clearly laid out.
Feels like IGBTs are the secret sauce and we don't know what that stands for let alone the physics behind them. Of course I'll hit Google, but might be nice to include. But still, neat video. Thanks!
The logic of IGBT's are identical to transistors. (Not the mode of operation, but the logic.) Ie, a signal is sent to one pin, thus opening flow in one direction between the other two pins. If you want to understand how IGBT's work, start by looking at how diodes work, and understanding the quantum physics at play there, then go to transistors, then IGBT/MOSFETs.
StringerNews1 There absolutely is physics involved quantum physics to be exact. The definition of physics is not moving parts, thermodynamics and lots of other physics do not involve moving parts
As far as I'm concerned, an IGBT basically operates like a BJT and a MOSFET stuck together with gaffer tape. The MOSFET (which needs zero gate current, but has medium resistance) turns on the BJT (which is low-resistance but thirsty). Combining them in semiconductor is complicated, but their operation is not too obtuse
I came here for a review of inverters but instead got a course on electricity. They finally got to my interest in minute 6. I always wanted to find someone to explain my modified sine wave inverter vs my full sine wave inverter. Thanks
...wow I did VCE physics and you made me understand this concept in 1 video so much better than 2 whole years of the subject at school 😅 Totally wish I'd found this channel sooner. Thanks bro 🙏 Keep up the good work
I don't know why, but this video is so well done that it actually made me angry for a minute. Bravo! I hope you're incorporating the battery example in basic AC/DC theory lessons. The animation with the simplified IGBTs is spot on, great job by everyone involved!
Wanted to learn how my UPS works, learned how electricity actually works instead. You explained this so easily and effortlessly. No one at my college would have explained it like this. Great video. Subscribed.
I use a power inverter while camping or as a emergency power supply during bad storms when the power goes out, your videos are phenomenal and brake stuff down so well to understand it
.. seriously though!? This video doesn't even provide a basic circuit showing how the input DC has to generate a sine-wave (or a rudimentary square wave for simple low power applications) There used to be plenty of circuit diagrams available in the '70s and '80s in publications such as Hobby Electronics, Electronics Today International and Elektor magazine - these would show how a square-wave oscillator could drive a couple of power transistors (2N3055 with heatsinks) connected to a mains transformer in 'reverse' - it was easy to demonstrate how a 12v supply could be made to produce a 50hz a.c output at 220~240v into a low load (around 40~50W) Kits were also available for hobbyists for various applications ie. portable 220v a.c supply to power a synchronous motor for a telescope that had a camera attached for real-time tracking.
HOLY crap what a helpful video. I’m in welding school and just have been trying to piece everything together over the months and this is so helpful with this topic.
I am a retired engineer, worked in telecommunications field, engineering digital central telephone exchanges. Most of exchange equipment powered from 48V batt supply which were charged by rectifiers fed from the Building AC supply. But some equipment in the exchange office needed protected 120VAC ( Terminals , Test equipment, Modems), supplied by inverters mounted on Misc racks.
Well done young man. Thank you. I worked on inverter repair and saw first hand what a high power inverter does when the DC link circuit is shorted. BOOM! lol!
Really great videos! Now since you have several videos about inverters and VFDs, explain how the controller works please? It’s the thing that make everything work as beautiful as it does after all, thank you!
4:13 Side note: Not all synchronous generators have a permanent magnet in their rotor. Some use a circuit fed with DC instead to produce a steady magnetic field, working as an electromagnet. 4:17 The electrons in the winding don't get pushed just because the magnet has a polarity. If that was true, holding the magnet still should also make the electrons move, since the magnet still has its polarity; but in reality this won't happen. The real reason why the electrons move is because the magnetic field of the magnet (or electromagnet) is _changing,_ thus inducing an EMF in the windings. At 4:37 you explained it correctly. 9:48 Even though the phase is split, it's still just a single phase, since the voltage or current in both live conductors are in phase (or 180° out of phase.) To be considered as two phases you'd need a phase shift between the current in the two live wires, i.e. 90°. Anyways, I understand what you meant to say. ;) 10:13 In general, the coils/windings of the generator aren't inserted 120 physical degrees (A.K.A. mechanical degrees.) In fact, in the generator you showed the angle between two adjacent coils (of different phases) is 360°/6 = 60°. Real generator have more than one winding per phase, so they're inserted at angles much less than 120 mechanical degrees; you can google about Ferrari's theorem. What is true, is the set of three output voltages are 120 electrical degrees shifted.
Yes this is very easy to understand than most UA-cam lectures. When I see aAffinity reality and good Communication which equals understanding. Read fundamentals of thought To get a better understanding of what I mean. Good work thank you
It's amazing how overall little common person needs to know in life to get by in modern society, all the hard work and details handled by subject matter experts. All I know, flip the switch to turn lights on as that is not my expertise, but I can explain how to program and handle DBMS to the dot as that is my subject. Individually we are nothing, but collectively we are modern scientifically most advanced civilization ever existed on planet earth.
Very good information. A question for you, How does a pure sine wave inverter work? Some electronic equipment will not work with normal inverters. Thanks for your time.
The part I keep getting stuck at is *smooth* AC. Smoothing to DC with the rectifiers and a cap is fine. But, in inversion we've got PWM chopped to 'Sine-like AC' ... but it's rough. Inductors? Something clever?
Just add the correct amount of inductance and capacitance to the output, I'm not really sure why that was left out... Makes me wonder how much important stuff like that is left out from other videos where I don't know much about the topic.
This is also a UA-cam video, not a patent on how to build a nuclear powered goggle-flop flux capacitor. It's to give you a general understanding of the topic, not how to specialize your career in a specific sector of an industry.... 😂👍😝
I think more accurate PWM would be enough for most. After all many applications will work just fine with imperfect AC voltage, so they problably work with imperfect sine waves too to some point. But if for some reason we would have to have as perfect sine wave as possible, maybe we could then just run DC motors to generate AC? Definitely noticeable energy losses but it would work and wouldn't differ from power plants. :D
@@insoYT you can also get faster switching or "smoother" sine-wave output from decent equipment. I have Telco equipment that runs on DC and some that run on AC. We have some decent enterprise UPS' that claim 'clean sinewave' (no oscilloscope to verify). So clean that sensitive equipment doesn't complain about faults or dirty generator power when we have to cutover.
James S I agree, it is just a UA-cam video to give general understanding. What I don’t like is that the video makes it seem like, yes this all you need to do to make the output identical to traditional AC generation. I wouldn’t care if it was just a mention of “this is close enough for nearly all applications, but it’s not exactly the same”
This is one of the best videos on the subject! Only, at 4:33 I think we are giving the wrong impression with the magnets and electron relationship. I believe it is the moving magnetic field that causes electrons to flow and not the 'attraction' of the magnets 'pulling' and 'pushing' the electrons. Perhaps you felt that by saying 'pushing' and 'pulling' it would adequately cover the point allowing you to move forward to the other, more important and relevant-to-the-video ones. All-in-all, I found this very helpful. Thanks.
It is not gaps ... there is power .. take the V square ... but the power signal has gaps, not the voltage signal so we fill these gaps by other phases power
Youre experiencing the dunning kruger effect* (or however you spell it). Youre going towards the pit of confidence but dont worry after you pass that pit, your confidence will increase with the increase of knowledge. If you dont know about this, i'll try to explain it the way i understand it. they (dunning and kruger) observed how people with different levels of knowledge displayed confidence. People with no knowledge had no confidence, people with (overall) little knowledge had a lot of confidence (i get to explain this a bit later). people with with moderate knowledge had a lot of doubt. And the experts had a lot of confidence. The graph kinda looks like this _/V. As people start learning about something their scope of the overall knowledge starts out small so they believe they have conquered a high percentage of all knowledge to be had. That is until they realize that there is a whole lot more to what they do not know, thats when their confidence start to fall. And it will fall more and more until they have the full scope of the knowledge to be had. Kinda like moving the goal post further and further until it doesnt move anymore. And as they continue to learn, they get closer to the goal and that builds confidence.
Are solar golf carts as bad of an idea as I believe it is a good idea? It seems like a better way to make sure you are off the course before dark and maybe save a golf course some electricity bill by leaving solar carts outside the cart barn where they usually get plugged into to charge for a full day of tee times

This guy's job is incredible. It is extremely informative and playful.
Thanks, Rafael! Glad you enjoyed, thanks for supporting us
Me to appreciate this animated video better than explained by a professor.
...wow
I did VCE physics and you made me understand this concept in 1 video so much better than 2 whole years of the subject at school 😅
Totally wish I'd found this channel sooner. Thanks bro 🙏 Keep up the good work
I don't know why, but this video is so well done that it actually made me angry for a minute. Bravo! I hope you're incorporating the battery example in basic AC/DC theory lessons. The animation with the simplified IGBTs is spot on, great job by everyone involved!
Excellent explanation. I understand this far better than I did 20 minutes ago. I am now a believer and a subscriber.
Who watch this video in 2024
No one. Only you. You’re the only person all year to watch this video

I have not seen this kind of explanation anywhere else. A million thanks for the upload!
Wanted to learn how my UPS works, learned how electricity actually works instead. You explained this so easily and effortlessly. No one at my college would have explained it like this.
Great video. Subscribed.
An UPS has an onboard power bank, which supplies backup power when the main power is cut.
I use a power inverter while camping or as a emergency power supply during bad storms when the power goes out, your videos are phenomenal and brake stuff down so well to understand it
Amazing video!!! If we had theese videos 20 years ago when i was arlt college, life then would be far easier!
This was amazing! 4 years of engineering summed up in 13:38 mins! Enjoy the coffee my friend
.. seriously though!?
This video doesn't even provide a basic circuit showing how the input DC has to generate a sine-wave (or a rudimentary square wave for simple low power applications)
There used to be plenty of circuit diagrams available in the '70s and '80s in publications such as Hobby Electronics, Electronics Today International and Elektor magazine - these would show how a square-wave oscillator could drive a couple of power transistors (2N3055 with heatsinks) connected to a mains transformer in 'reverse' - it was easy to demonstrate how a 12v supply could be made to produce a 50hz a.c output at 220~240v into a low load (around 40~50W) Kits were also available for hobbyists for various applications ie. portable 220v a.c supply to power a synchronous motor for a telescope that had a camera attached for real-time tracking.
Thanks sir! Crystal clear explanation. The animation made it easier to comprehend.
The best video that’s teach power convertrs in a sample way .. I’m sure that’s I’m going to learn a lot of stuff in this Channel .. 👍🏻
That's the power of passion. You explained it better than every book written on the subject.
I've had this explained to me numerous times and never quite got it. This explained it perfectly, nice one!
Such a beautiful narration to go with an equally brilliant animation!
HOLY crap what a helpful video. I’m in welding school and just have been trying to piece everything together over the months and this is so helpful with this topic.
Finally I understand phases now thanks to you, yay
I am a retired engineer, worked in telecommunications field, engineering digital central telephone exchanges. Most of exchange equipment powered from 48V batt supply which were charged by rectifiers fed from the Building AC supply. But some equipment in the exchange office needed protected 120VAC ( Terminals , Test equipment, Modems), supplied by inverters mounted on Misc racks.
0:48 FULL BRIDGE RECTIFIER
Electroboom.......
More like recti-fire with him lol
Mehdi fans
ahahahaha same thing i have in my brain when someone say bridge rectifier
Ah, I see you're a man of culture as well
One of the best videos on basic circuitry I have ever seen.
Very well explained, animation makes everything crystal clear, keep it up
You have the gift of simplifying things to make it easily understandable. Thank you.
OK, this was really well explained.
Thank you
Well done young man. Thank you. I worked on inverter repair and saw first hand what a high power inverter does when the DC link circuit is shorted. BOOM! lol!
I've watched a couple of inverter explainers but this was the absolute best one, very clear explanation!
This you tuber deserves more subscribers and viewers than it has. Good explanations with a little bit creative examples.
Thanks, glad you enjoyed. If you can share one of our videos with a friend that would be a great help.
Really great videos! Now since you have several videos about inverters and VFDs, explain how the controller works please? It’s the thing that make everything work as beautiful as it does after all, thank you!
No wonder I subscribed, these videos are fantastic. You can explain electricity and electronics on all levels from basic to expert.
Thanks bro, you make everything clear and easy
Very well explained . The inverter is a power sequencer !
4:13 Side note: Not all synchronous generators have a permanent magnet in their rotor. Some use a circuit fed with DC instead to produce a steady magnetic field, working as an electromagnet.
4:17 The electrons in the winding don't get pushed just because the magnet has a polarity. If that was true, holding the magnet still should also make the electrons move, since the magnet still has its polarity; but in reality this won't happen. The real reason why the electrons move is because the magnetic field of the magnet (or electromagnet) is _changing,_ thus inducing an EMF in the windings. At 4:37 you explained it correctly.
9:48 Even though the phase is split, it's still just a single phase, since the voltage or current in both live conductors are in phase (or 180° out of phase.) To be considered as two phases you'd need a phase shift between the current in the two live wires, i.e. 90°. Anyways, I understand what you meant to say. ;)
10:13 In general, the coils/windings of the generator aren't inserted 120 physical degrees (A.K.A. mechanical degrees.) In fact, in the generator you showed the angle between two adjacent coils (of different phases) is 360°/6 = 60°. Real generator have more than one winding per phase, so they're inserted at angles much less than 120 mechanical degrees; you can google about Ferrari's theorem. What is true, is the set of three output voltages are 120 electrical degrees shifted.
Ofcos he knows this but he can't go to indepth otherwise it will complicate the video
Yes this is very easy to understand than most UA-cam lectures. When I see aAffinity reality and good Communication which equals understanding. Read fundamentals of thought To get a better understanding of what I mean. Good work thank you
Fantastic video... thanks for your work.!
This is great. The Pulse Width Modulation shows how the traction motor inverter works on an EV as well.
Nice explanation and illustrations! That answered questions that I always had about the conversions. Nice job, thanks!
We use inverters in my lone of work, hvac and refrigeration quite a bit. This was helpful. Thank you!
It's amazing how overall little common person needs to know in life to get by in modern society, all the hard work and details handled by subject matter experts.
All I know, flip the switch to turn lights on as that is not my expertise, but I can explain how to program and handle DBMS to the dot as that is my subject.
Individually we are nothing, but collectively we are modern scientifically most advanced civilization ever existed on planet earth.
Very good information. A question for you, How does a pure sine wave inverter work? Some electronic equipment will not work with normal inverters. Thanks for your time.
Very understandable, if you want to understand it. Great work.
@1:24 Answer: e bike battery charger.
Nice
Rectifier video here ua-cam.com/video/RiRyzLl4Y8U/v-deo.html
All the worries of not knowing and feeling anxious about upcoming test just vanished! This video clears everything up. Thank you 😭
Wow, i was just looking up a bunch of stuff about inverters.
I wish UA-cam and these guys had been around when I was studying electronics.
How does the controller work that times the opening and closing of the transistors?
computers and controllers are basically calculators, they do these types of calculations way faster when you load a video or play videogames
You supply AC/DC current of awesomeness ! Thank you and Keep it up !
The part I keep getting stuck at is *smooth* AC. Smoothing to DC with the rectifiers and a cap is fine. But, in inversion we've got PWM chopped to 'Sine-like AC' ... but it's rough. Inductors? Something clever?
Just add the correct amount of inductance and capacitance to the output, I'm not really sure why that was left out... Makes me wonder how much important stuff like that is left out from other videos where I don't know much about the topic.
This is also a UA-cam video, not a patent on how to build a nuclear powered goggle-flop flux capacitor.
It's to give you a general understanding of the topic, not how to specialize your career in a specific sector of an industry.... 😂👍😝
I think more accurate PWM would be enough for most. After all many applications will work just fine with imperfect AC voltage, so they problably work with imperfect sine waves too to some point. But if for some reason we would have to have as perfect sine wave as possible, maybe we could then just run DC motors to generate AC? Definitely noticeable energy losses but it would work and wouldn't differ from power plants. :D
@@insoYT you can also get faster switching or "smoother" sine-wave output from decent equipment. I have Telco equipment that runs on DC and some that run on AC. We have some decent enterprise UPS' that claim 'clean sinewave' (no oscilloscope to verify). So clean that sensitive equipment doesn't complain about faults or dirty generator power when we have to cutover.
James S I agree, it is just a UA-cam video to give general understanding. What I don’t like is that the video makes it seem like, yes this all you need to do to make the output identical to traditional AC generation. I wouldn’t care if it was just a mention of “this is close enough for nearly all applications, but it’s not exactly the same”
This is one of the best videos on the subject! Only, at 4:33 I think we are giving the wrong impression with the magnets and electron relationship. I believe it is the moving magnetic field that causes electrons to flow and not the 'attraction' of the magnets 'pulling' and 'pushing' the electrons. Perhaps you felt that by saying 'pushing' and 'pulling' it would adequately cover the point allowing you to move forward to the other, more important and relevant-to-the-video ones. All-in-all, I found this very helpful. Thanks.
Awesome content .... appreciate your effort to explain the things in such a simpler manner. Great job ..
Hats off to you and the way you explain..... Thanks a lot. 👍👍👍👍👍
1:23, trying to better understand the concept in order to simulate a UPS system
Mindblowingly simplified even for the average person, thanks a lot 🔥
I've seen so many tutorials of how inverters "work" but never seen how the pwm controller works in that inverter, how it's built
Great video... You made it very simple to understand the complex concept!
It is not gaps ... there is power .. take the V square ... but the power signal has gaps, not the voltage signal so we fill these gaps by other phases power
There are power gaps in single-phase ac. Any instant that either voltage or current is zero, power is zero.
your explaining is amazing! in fact, my English isn't really well, but i've already understood a lot
6:13 IGTB nice
Learned more here than 4 years in uni and 4 years in a power transmission company. Wish I'd seen your video 13 years ago.
Here I go again The more I learn the less I feel I know
Youre experiencing the dunning kruger effect* (or however you spell it). Youre going towards the pit of confidence but dont worry after you pass that pit, your confidence will increase with the increase of knowledge.
If you dont know about this, i'll try to explain it the way i understand it. they (dunning and kruger) observed how people with different levels of knowledge displayed confidence. People with no knowledge had no confidence, people with (overall) little knowledge had a lot of confidence (i get to explain this a bit later). people with with moderate knowledge had a lot of doubt. And the experts had a lot of confidence. The graph kinda looks like this _/V.
As people start learning about something their scope of the overall knowledge starts out small so they believe they have conquered a high percentage of all knowledge to be had. That is until they realize that there is a whole lot more to what they do not know, thats when their confidence start to fall. And it will fall more and more until they have the full scope of the knowledge to be had. Kinda like moving the goal post further and further until it doesnt move anymore. And as they continue to learn, they get closer to the goal and that builds confidence.
Amazing. The animations make this whole subject so much easier to understand.
Are solar golf carts as bad of an idea as I believe it is a good idea? It seems like a better way to make sure you are off the course before dark and maybe save a golf course some electricity bill by leaving solar carts outside the cart barn where they usually get plugged into to charge for a full day of tee times
Honestly sounds like a great idea
great start to new innovation sir Richard
Seen our new video on HOW SOLAR PANELS WORK in detail ua-cam.com/video/Yxt72aDjFgY/v-deo.html
💪💪💪I feel more knowledge when I watch videos from this channel 😍😍😍
This was overkill! Love this, gotta buy a coffee or somethin'
You have the best explanations on the internet
Who’s watching this video in 2027?

How superbly explained with simplicity....
U r the best ever I learnt from
Anyone else scrolling through the comments to find South Africans?
Not really but found you anyway
Not actually, but if u were looking for a Brazilian then u found one
someone @ Elon musk
Yep❤❤
Lmfao😂 here we are
The best explanation I've had. I only needed this video to understand the entire concept.
I have a dream to develop a project for a off grid house power supply with a output of 40 kWh with no batteries, just using a large set of electrolytic capacitors.
Well, I need a lot of help.
40KWH! start with 400W and see if it works
@@EngineeringMindset So... first of all, I'd like to congratulate you for the marvelous work presented here throughout these incredible videos.
About my intended project, even with my lack o knowledge related off grid schemes, I already measured the behaviour of inverter and electrolytic super capacitors with out puts under 1000 W.
My goal is build a big one stable and powerful enough to run a big house even during the winter.
Cheers
Upload some videos to your channel, I'd like to see how your projects comes along
Thanks alottttt!! You have no ideas!! All your teaching are perfect!!!
I had a 100W invertot for my dad's car, and I destroyed when I was 5 yr old. I just dropped from the car...
What an ingenious piece of engineering! The video was very informative, thank you!
