How Inverters Work - Working principle rectifier
Вставка
- Опубліковано 14 сер 2024
- How inverters work. In this video we take a look at how an inverter works to convert direct current (DC) into Alternating current (AC). Inverters are used increasingly throughout industry as well as building services HVAC systems to achieve precise control of AC induction motors connected to AHU fans, compressors pumps etc. Inverters are also used within photovoltaic arrays to provide AC power for use in homes and buildings. In this video we start at the basics to understand the difference between AC and DC power and then look at a simplified example before moving onto an advanced pulse width modulation (PWM) example to see how the load experiences and AC supply from a DC source by converting the direct current into a sine wave.

Plz tell how IGBT and MOSFET works plz
See my new MOSFET explained video here➡️: ua-cam.com/video/AwRJsze_9m4/v-deo.html
All i have to say is just WOW! I've never met such a thorough and still easy to understand explanation! This is thanks to al the graphs, pictures and analogical examples! Love your work, man!
I wish all schools could be teaching like you we would be having an advanced civilization visiting mars like in a backyard
I feel reborn after finding this channel. It's a shame it took me so long. Hands down best channel on the subject.
reborn is a perfect word for it
This is by far the best explanation ive seen of this for beginners thank you for this info.
I am doing this at university and this video has helped me understand hours of my lectures. Thank you!
Watching different video's on this topic because sometimes different methods of explaining can help embed learning but I find this series very comprehensive. Well done & Thanks TEM!
really really good demontration and simple explanations for what not explained in schools like that!
Very interesting way of explanation, and super concentrated information with supportive real time animations! Really highly appreciated! Thank you very much 👍👍👍👏👏👏
When people create content that shoot for this >>>>>>> Thank you from the bottom of my Heart .. You did a very good Job!!
Nice video
A couple of minor things.
It's important that one set of switches open before the others close. If closed before open (as narrated) then a short circuit will result and the IGBTs will disintentegrate. It's called shoot-through.
In the 3 phase animation, the active Mosfets should swap to the other pair for the negative half cycle. :-)

Super informative, well presented and easy to understand. Thanks!
Quite literally one of the best channels on UA-cam.
I've worked for Danfoss Dives NAM for 15 years and just took on an electronic tech position. Imagine my surprise when this video was sponsored but my company. ❤️ I appreciate your videos very much.
Great to hear. We actually have a newer version of this video, better graphics and explanation, check it out
The best channel to learn electrical engineering........ I am not an engineering student... but your way of teaching is so easy and knowledgeable that even a non engineering student can also understand it ..
Amazing. I install these heat pumps and have been to several of the manufacturers training seminars. I still never understood what was going on, why they where called inverters or what pwm was used for. This makes sense to me now.
This is the answer i needed which even google cant give me thank you.
Awesome! Thank you for spreading knowledge to guys like us who are in other streams of engineering and desperately wants to know how these electronic equipment works! Thank you!
What stream of engineering are you in?
Mechanical Engineering....
I rarely comment on people's video but I wanted to say your video are great and very informative.
Great video. Thanks. One minor correction: 60 Hz electricity has 120 polarity reversals per second, not 60.
dis traktor always that one guy.congrats you're cool
@@BuffaloWings713 yep!but somehow that one guy often crystallises the knowledge for others 😉
An Important point that I would like to mention is that the identifying attribute of a DC is that it flows in one direction but, it is not always at it's peak. For learning purposes, ommiting the fact that DC can fluctuate at specific frequencies and transmit data signals is convenient as to not confuse new learners. Although, to say that DC is always at it's maximum is simply not correct as a definition.
Great content btw! Glad you are able to make such excellent educational videos.
Good to see you have the electrons flowing in the correct direction. People please keep in mind that if the diagram simulator was showing conventional current, the diagram simulator (not reality) would be flowing in the opposite direction. In reality electrons flow out of the negative source when power is being used. This is important because the direction of electrons over a resistive load determines the positive and negative voltage potential differences induced on the terminals of the resistive load.
My dad was an engineer and I've been really curious about how our solar panels work and he mentioned an inverter converting the voltage from the panels which I think was about 12 and comes out 220 to make our television work. He couldn't explain how inverters exactly does it so I've been searching for it. Since I dont study engineering (im still at highschool) I cant fully understand this but it gives me the idea how it really works maybe I should start learning the very basics before this
Seen our new video on HOW SOLAR PANELS WORK in detail ua-cam.com/video/Yxt72aDjFgY/v-deo.html
Just subscribe , first timer.. i am joining in because i love this field..
Very great videos! Only thing that may help non-engineers (by trade) is the pacing of the video can be fast between topics and main points for this processing the information. Really love the presentation and explanations. Thanks!
Now this video explains it very good. Not too technical. A example for non engineer person.
Excellent. I kind of understood the technology but now I understand much better. Thanks.
Thank you for the video ❤.
Truky appreciated
Just brilliant! I always wondered about how the sinusoidal curve was obtained

Thanks sir for this kind information. Once again Thank u
thank you for your hard work ,you always save us
It is a Shame that Most USA public school systems do NOT actually Cover this at all .... Time to change the whole superstructure
Thanks for your support to understanding power electronics..
Learning a lot from your videos, Paul !
It's a magical box that makes the pixies dance back and forth
MWB Gaming nice profile photo 👍
@@cheguevara5121 cheers mate, glad I'm not the only one who knows the truth
Wow, I understood that on the first attempt. Thank you! So what you are saying is that the circuits gates are allowing negative and positive current through their gates from the battery in alternating pattern simulating AC current, therefore becoming AC current since they are coming from two different circular paths of directions.
Thanks for this.just brilliant.
Excellent work worth a coffee.
Thanks for your support, Paul. Much appreciated ☕
Very nice explanation. Easy to understand with animations. Thanks a lot for making a video on this topic.
Very well presented, awesome video my dude please make more videos on electrical engineering
This channel is solid gold! 💪🏽👍🏼👍🏼
Non-engineer here.., I feel like I am understanding it to a point. If you are using the PWM to vary the speeds of an AC motor, wouldn't this put a lot of stress on an AC motor that was designed for 50 or 60 HZ? Or do these need to be more robust AC motors designed to take the stress or variable frequencies?
Awesome informative video! Thanks!
brilliant explanation
I like this channel!!!! Thank you kind sir for helping the half experienced wire guy!!! I don't engineer stuff but I do hook allot of electronics up.
So here is a question for you how do galvanic isolators work and why are they needed
Your lectures are far better than university lectures 😂.Keep uploading sir
Great video! Thank you!
Very interesting. I spec out those VFDs at my work often, but had no idea they temporarily rectified the AC current to DC so that they could manipulate that with an inverter. Cool.
Power inverter video here ua-cam.com/video/iIqhAX0I7lI/v-deo.html
I love your videos and how you explain things! Thank you for this series!
Could you make a video that explains how basic household appliances work? Things like a microwave, refrigerator, coffee machine, electric fan, or HVAC? I know it's basically converting electric energy into the specific kind of energy an appliance uses to do its job, but how does that conversion happen?
You explained light bulbs (lamps) as an example, and that's just electric current running through a wire of a specific material that produces light energy at a certain temperature.
EDIT: Just finished the video. That's amazinggggggggg why don't we learn about this stuff in school???
Wow!!! Just wish that this existed when I was in school.
Check out our new version of VFD or power inverter explained, even better
Great video, I would love to see you explain how pure sine waves are generated by an inverter.
This is how pure sinewave inverters work. They are never really pure, just a reasonable approximation. The modern mains supply is never really pure either.
@@andrewwhite1793 exactly ,perfection in sub systems is rarely found; one wonders if there are defective atoms or photons for that matter.

Please give me a clear explanation on example a 5V bridge rectifier. Also about a transformer less power supply.
Rectifier video here ua-cam.com/video/RiRyzLl4Y8U/v-deo.html
Great explanation
exellent demonstration. thanks alot
Informative, significant topic and Useful, however I don't think he explains what the abbreviation IGBT stands for?
Insulated Gate Bipolar Transistor, Part Mosfet, allowing a low power driver circuit, part bipolar transistor, giving low ON resistance :-)

Wow this is genius.
Thank You! I understood. But! Where is the neutral?
We r with u you go more indepth like this
Please upload the videos with subtitle, it will help us to understand. Tnx.
You can turn subtitles on from your device, they are available on every video
Your videos are very informative
How do you do that, so impressive brother.very informative and out of the box.
thank you!
very informative...thank you
Finally a non indian explanation of inverter....
Wow great tutorial...
it is possible to save electricity if i used ac to 12volts adapter to inverter = AC output ?
rather than use our AC plug directly ?
Power inverter video here ua-cam.com/video/iIqhAX0I7lI/v-deo.html
What book do you recommend to learn about electricity, grounding, why the outlet has a 0V if the current is alternating?
Electricity 1-7 by Harry Mileaf is a good choice for understanding the basics of electricity. It's old and a bit pricey but I have heard a lot of good things about it.
Very Nice, Very Nice
Classic and simple.
Awesome video and explaination as well 👌
Glad you liked it. We have a newer version called power inverters explained which it quite a bit better
@@EngineeringMindset ok, I will see that also, good to see your reply,
Awesome 😊
please make a video on dual inverters, I don't understand how they work and what's their benefit
If I've understood correctly, I think the animation should show the top of the first half bridge and the bottom of the last half bridge switching when the waveform polarity is negative?
Great job and also I would like to learn more about automotive Rev Rev limiters could you explain please
Are you old enough to remember the old fashioned vibrators that were used in tube car radios of the fifties? Your beginning illustration shows how the vibrator worked. The one of the output fed a step up transformer, the a second set of switches would take the output of the transformer would then be used to un-alternate the output of the step up transformers to feed the filtering network then to the tubes. Selenium and silicon solid state rectifiers did no exist at that time!
Can you do a video explanation of how ac to dc works?
What component doesn't allow AC to pass? An inductor...
Oh and also igbts. He explains it at the end. Pay attention grasshopper.
Actually PWM for ac motors works in a slightly different way.Since lowering the power won't affect the speed of the motor but just the torque PWM works on the frequency it does something like sending a full positive wave skipping the next negative,the next positive and then sending the next negative....it kinda allows one half of the wave form stops the next 2 allows the 3rd and so on....this way the frequency is basically reduced to 1/3 from 50hz to something like 18 hz slowing down the motor
Oscilloscopes are definitely usefull. Used them for auto tech.
Very interesting.Thanks.
