It's been over a year and a half since this video was posted, I'm going to assume part 6 just isn't happening. It's a shame, I found this series to be one of the best I've seen on UA-cam and that's really saying something. As far as I'm concerned this along with your power grid and motor videos tops anything Dave Jones has ever done. I understand these videos take a lot of time and energy, and you can't turn it into a full time job, but I really wish you would go back to this type of content. I find the small projects to be interesting, I have a hard time getting into the lab reports, and I think the only thing that is going to come out of the EDM project is a boost in AVE's Patreon income. On the other hand, the videos where you delve into the theory and inner workings of the subject matter are fantastic because you are so damn good at it. Just one subscribers opinion for what its worth.
Please I beg you to continue this series! Please!!! This is the best explanation I ever found.
I remember sitting in a classroom nearly 40 years ago with the lecturer trying to explain this. I never really grasped it. I went through it over and over again, but it never really clicked. So I watched your video once, and everything fell into place. Thanks. It's so easy when you get someone to explain it the way you do. Great work and its much appreciated.
Dave Pye Hey I appreciate your kind words :) It really makes me happy to know that my videos do actually seem to help people of all age groups in so many different countries to understand ideas which seemingly a lot of teachers failed to convey. Thank you for sharing the videos by the way. I really could use more viewers :D
I am an electrical engineering student, I wish my instructors at the university can teach like you, you are amazing man thaaaaaaaaaaaaaank youuuuu!
I am waiting tutorial (6) thank you again
This covers hours of physics classes, and you actually understand everything! I think every teacher should come here and take lessons on how to teach.
32 hours well spent you've created the best tutorial for magnetic circuits I've seen so far
Well done
The quality of this presentation far exceeds any school's offerings. The fact that you can explain such a complex idea in a second language with such great success is nothing short of incredible! I look forward to all of your upcoming videos :) vielen dank!
I am left with nothing but awe. The level of detail is superb. Learning has a total different meaning now. How can I show my gratitude? Thank you!
xDR1TeK Well I'm glad I could be of service :)
If you want to help me producing more videos, you can donate a few bucks.
You can find a paypal donation link in the "about" section of my channel.
This is TRUE Academic material provided here! Even better explained than that of a typical Educating Institution. You should clearly try for a PhD and teach E.E.When i stop being unemployed you definately get a donation from me as well. You are more than worth it!
(Also, where is the 6th part?)
Please post the nest part as soon as possible the part 6... This is the best tutorial of SMPS I've ever seen.
I've been looking for part 6 but couldn't find it, has it been uploaded. These videos are very helpful, thank you!!
You do not only a great job of explaining all of the scientific theories, laws, ideas, etc., but your production value on your videos is very high and show that you put a lot of care and work into their production. I appreciate that very much, since video and film production is my particular professional specialty
In my opinion, the best one yet. You're doing a better job at explaining this than my teachers ever did, keep it up. Another video on inductance and inductors is definitely warranted, though; I'd wager that knowledge about basic magnetics is rather more obscure than knowledge about basic electronic circuits.
with your confident voice you have completed fifth episode,with your creative and innovetive thinking ,it amazingly cleared all our doubts THANKS FOR YOUR EFFORT.
This is probably one of the best videos I've seen online for explaining inductors..
Those videos are pure gold. Thank you for all the time and hard work that you put into making these. You have a great ability to disassemble complex matters into small, digestible modules and then serve them in the correct order to build the idea from the ground up. I take my hat off to you.
Your videos are really well done! I am amazed at how organized and clear all of your presentations are. I've never heard a clearer explanation of inductors. Thank you for taking the time to do them. They are extremely helpful. You are the best teacher ever.
Now, I am eagerly awaiting SMPS Tutorial #6.
Thanks for explaining things so practically. I've known the formula's for a long time, but knowing the formula's doesn't guarantee that you really understand what is going on. You do a great job communicating what is going on. So even after four years of university I finally learned a lot. Big thumbs up!
Great series thus far. Genuinely learning a great deal. I am fairly aware of a lot of the properties you talk about but you are just tying it all together so well and introducing such powerful analogies that my understanding is growing by an order of magnitude. Adding the 'spark' to make the leaps in concept required.
Thank you for putting in so much time and effort. I sincerely mean that.
Hi, congratulations with your five detailed SMPS video's. I saw all of them and I was impressed. Waitng for number six now.
This is the first page i actually subcribed to on youtube after years of browsing. After three years of phsyics at the university, this series is the best comprehensive and complete explanation of any design/theoretical piece i have come across so far.
Please do keep up this good work, i find it absolutely amazing!
I appreciate it very much. I will continue this series soon and I hope that I can keep up with the high standards that I have set for myself.
Your video tutorials are the best! I appreciate the time involved in putting this series together and look forward to the continuation of the series. I learned so much about magnetism and what it really is, especially the similarity between electrical circuits; and I have worked in electronics for almost 50 years.
One of the best tutorials I've seen on the internet. Thanks for posting.
Its sometimes really frustrating in college when your instructor listening you explaining those things instead they are the one who supposed to explain to his student. Thanks so much for these videos. I really understand and learn a lot. hope to see more videos. God bless
Such a great video series! Thanks a lot for your hard work, it really shows in the videos. Very clear explanation and build-up, well thought through.
Without begging or trying to push you in any way, this series deserves a part 6 someday :)
I'd like to add to the comments posted here in saying that your videos have more eloquently and approachably illustrated the engineering principles behind electrical hardware than my university courses. The effort you've put into these videos is very appreciated. Looking forward to the rest of the SMPS series!
Yeah, agree with Pavel - this content is one of those rare nuggets of information. Your 32 hours of hard work is greatly appreciated. Would love to see more in this series.
Good video! Very clearly explained. When I first learned all this stuff, it might have taken maybe an afternoon of reading and thinking to understand it, but you've compressed with into 26 minutes.
It's clear what it implies about air gaps in transformers as well, how the whole transformer is basically defined by the gap rather than ferrite because it is the majority reluctance is often not immediately apparent to a beginner.
Very well done.
@The Post Apocalyptic Inventor : Yours is the best electronics tutorial I have ever seen. You are doing a great service to the budding Analog guys by teaching. I loved every video. Please post more. You made me look at an Inductor in a different way!!
It's been a year since part 5 was released: I realize creating a series of this scale and complexity must be difficult but I sincerely hope to see videos about the other basic types of SMPS systems in the future. I have joined your Patreon & look forward to learning much more from you!
Very much looking forward to video 6, looks like it'll be the most interesting video in the serires.
Your time was not wasted in the least. This series so far has been much more informative than my university classes on the same subject. I can't wait for the next one and if I could donate I already would have. I appreciate your time and efforts to put these together to expand the knowledge of thousands. Bravo!,Subscribed!
shadowwolf225 Well thank you for the very positive feedback. The next part of this series will be uploaded within september 2014 and I guess it will meet the standards of the first 5 parts.
btw: If you ever find the money to donate a few bucks, you can find a donation link in the "about"-section of this channel. :D
The Post Apocalyptic Inventor The donation page defaults to German :) I got an error the first time, but then I realised that I had to use a comma instead of a fullstop for the decimal point. Thanks again for the vids.
The Post Apocalyptic Inventor Looking forward to part 6 . I am enjoying your tutorial videos.
I wish my physics teacher could have explained this as well as you do. You are a truly excellent teacher and I urge you to carry on with your tutorials as they are the best I've ever seen. Clearly explained and with fantastic graphics.
Thankyou so much for your very hard work. I look forward to part 6!!
Very good video series. Thanks! I did study SMPS theory at school, but seeing practical videos and simple explanations are very good addition to almost forgotten theory from 5 years back.
Well done and thank you for a great series. This series is aimed at just the right level for me - thank you. You somehow managed to get above "basics" and below "too technical", which I think is quite difficult to achieve. Clearly, many people like your videos already and I'll add my voice to that - please continue with number 6!
I just cannot believe someone can be so kind enough to make such useful and well made videos! You are amazing! Keep up the good work!
You're an excellent instructor sir. Thank you so much for sharing your valuable time and knowledge with us.
Really really thankfull for your video, i'm just a hobbyist and a student, watching your videos really helps and make me learn more. Thanks a lot lot!!!!!
you commented on the time and energy it takes to make these videos, and it sounds like a lot of work but it shows great job and thank you.
A fantastic tutorial for students and EEEs alike. The section on magnetic flux was a new area for me, and the level of detail was perfect, thank you!
You have a new subscriber!
Your method of explanation is fantastic👍👍👍
Plz upload smps video 6
Just finished watching the videos of SMPS series all at once. I must say, the best tutorial on power conversion I found. Your presentation style and skill doesn't need to mention that how much efforts you have given to make these great videos.
I also used to teach some electronics to beginner students and can understand that how much tiresome it can be to create demonstration and experiment circuits.
Hats off. Eagerly waiting for the next videos. :)
Your videos are awesome!
I have a working knowledge on these subjects as electronics are a hobby of mine and my day job is closely related to the field, but I newer have had a formal electronics education and your thorough explanations really help to _understand_ the wonderful laws of the world much better. And that kind of thing always brings joy.
I await the following part with much anticipation, and am grateful that you have made so much quality content on this subject!
I wish my teachers would explain this as good as you, all your effort was worth every second of my time!
Please continue your little school of SMPS beyond part 5.
I know you burned out with part 5, but part 6 is more engineering and part 7 till 10 are more and more exciting.
You are so talented for making electronics simple, native, please finish this serial.
Hard part is over, now do what you are best in. Engineering thinking and understanding.
Please, take a little of your time and put attention to magnetic and SMPS, you will be glad about yourself.
I am so much fan of intro in electronics through SMPS and your way of watching on things...
Your videos are awesome. I am a beginner in harvesting reusable components and doing different projects. Your videos have helped out a lot.
alright its not just fans you are showing knowledge too but also fellow inventors and in many cases you are provided a braces for the future of modern electronics. you deserve recognition for these efforts but at the same time will you deny yourself the same recognition? this series is undone and it has inspired me to another career how many others uve helped Idk. I will remember what uve shown but I look foward to what u will show. and how you will not be forgotten.
I love this series. I earned my BSEE back in 1976, and I love catching up with more modern technology.
Thank you so much for making this series. I am patiently looking forward to part 6, and then videos that go into more detail about boost/buck converters. You are very gifted at explaining this complicated material.
This is a great series! I hope you haven't given up on finishing it! Currently trying to fix a SMPS on a TV and am looking for what you have yet to explain, which is the actual SMPS with the isolating transformer :
This series of videos are AWSOME! You put a lot of effort to explain everything very clear, and you made it! Excellent job and keep doing it please!
Excelent videos, I hope you can continue with # 6.
32 hours is no surprise. But you covered a lot of ground that most text books do not explain well at all. You should convert these into a diagrammatic book. I would buy it at the drop of a hat. That would be another 300 hours later ;-)
what an excellent series of videos! it's many, many years since I first encountered the horrors of the SMPSU. I wish I had this invaluable guide to help my understanding.
The hard part is learning the terminology and jargon; made especially difficult by the many uses of the Greek lettering system. Once the vocabulary can be memorized and related to the corresponding electrical terms it is fairly straight forward to work with the equations.
On another note;
where are the other parts to this series!!! I remember going through and watching all the other videos MONTHS ago just to get to the end and realize that it wasn't finished. I realized that I had caught up to the latest and just had to wait. I just finished going through and slowly watching all the parts again thinking that by now it would be concluded. Only to find out that it hasn't changed for almost a year and a half.
You must know that I subscribed to this channel after only watching a couple videos due to the quality of the content; you make great videos so I wouldn't want you to rush and put out a half-assed attempt. I know these videos take much time and effort but know that these are some of the most important videos on your channel.
Maybe before you move on with the TIG welder project you should bring the rest of us up to speed on these SMPS's so that we can grasp your current/future reverse engineering better.
My ultimate SMPS goal is to build an AC/DC capable TIG/Stick welder with all the customizable settings a modern Inverter welder should have. I very much want to follow your journey; so please don't leave your students in the dust.
Thank you for all that you've done and will continue to do.
With regards...
Thank you very much. You explain very well and make it very easy to understand. Looking forward for part 6 of this series.
Again thanks a lot for your effort and time to make these videos. I am sure it will even cost some money to make these videos.... and we all know that you are doing this for us.
please continue this video series! it was very well structured and explained. Best i've found on youtube for describing the topologies you've covered.
Absolutely fantastic. Have subscribed, and will make a donation upon part 6 being released ;)
I can't thank you enough for your videos and in particular these SMPS series. Your videos are very clear and instructive and til now just the videoseries I needed to get myself more familiar with this subject and of course, electronics. A big thank you!
Fantastic tutorial about electric power conversion. How inductors and magnetic energy works is explained incredible good and easy to understood. Please continue with SMPS tutorial ;) Greetings from Croatia
This was freaking awesome. These are the kind of tutorials that are going to be linked to on youtube for years. Can't wait for the next part!
Very much looking forward to the 6th part of this tutorial! Thanks for making them.
I think physicists should learn to use descriptive variable names like a decent programmer. Greek letters are so outdated... Great videos. Thanks for sharing.
wow, you are the Werner Hercog of my favorite topics, anyone wanting to learn about these things should see your videos, very well explained.. and i love your post apocalyptic style :D
Thank you, I'm enjoying this series of tutorials.
TPAI: "making this video took me 32 hours..." Thank you for this information, I've wondered how much must go into such a well polished presentation.
Liked; subscribed; saddened to see that part 6 isn't available yet. Sent a few € your way. Not much, but maybe you can get a pizza or something while you work on the next one. Anyway, I look forward to it, but in the meantime will catch up on your other videos, as this is the first one I've watched.
Josh Webb Hey thank you very much for your support! I'm developing some new power supply circuits at the moment, but once that is done, the SMPS series will definetely be continued. Kind regards from Germany !
The Post Apocalyptic Inventor Thank you for making this video series, I am a student from India and I have shared this video with all of mine college friends we all love your work and are eagerly waiting for next parts..!! Regards.
Man, that was the best inductance basics introduction on the Intenet. Thank you so much!
Excellent presentation!
We've been waiting in earnest for the remaining parts of the series.
These videos are fantastic, you're helping create an online learning revolution that is freely accessible to all!
Danke, von einem Neuseelaender :)
I need to say, this was the most amazing explanation i've heard, because with all the experiments and the video content it makes so easy to understand, much better than reading about biot savart and ampere on a physics book. Nice! I am really looking forward for a next video. I wish i could donate to you, cuz you really deserve it, but in the state that my country is and the parts i'm buying for my next projects, 10 dollars is so much money. Keep it up!
This is the most informative video I have ever seen. Thank you for your time mate. Universities I have been to are f**in dollar oriented and take thousands of dollars for nothing. This is worth time and money (y)
Amazingly clear tutorial!!! Thanks a lot!!! I'm looking forward to part 6.
Thank you for your work! I really appreciate your teaching style, and look forward to more.
Thank you very much for taking the time to make this series of tutorials! You are awesome! I'm counting on you to finish the series as I want to design my own, high power SMPS, for use in my research on vacuum plasmas.
Thank you:)
This is excellent. Just made a paypal donation.
Excellent demonstration for everyone.
☺! WWWWWWWWWWWWW!
looks like Christmas presents! Hey Matt, Uncle
craig is quizzing me about your
gauss gun. wish you were here.
Great work....thank you for uploading video.......awaiting for the PART 6......
This video series is absolutely wonderful, thank you so much for these!
A huge thanks for the effort you took to made this tutorial series. Excellent explanation of topic...
keep your good work going please. I always check your channel fairly once a week to see any new updates :D. Very appreciate your hard work, bringing knowledge to people :D.
Excellent video tutorial about inductor. Hope you will make more videos like this one. waiting to see other SMPS tutorials.
Dude, you are awesome. Can't wait for the next video. Had this topic in uni. Boring from the first second to the last. But you found a way to make it easily understandable. Please keep up the good work!
waiting for part 6. I love this series, thanks.
hey really helpful video series, really appreciate your work and efforts.
I had shared links of your videos in my college, Me and my friends loved it and are always eagerly waiting for the next video.
Really getting excited about the part when we start building circuits.
thank you.
I appreciate your hard work in making these vids,they are very informative -though some calculations are somewhat over my head.Good job !
Amazing tutorial. I wish all my college professors could teach half as well as you can. Looking forward to the next parts of the series!
Majestic explanation. Contratulations!
Once again, Brilliant. I will have to go over this a few times. Thank you.
Thanks for putting these together. They are a great resource. Looking forward to the next in the series.
Awesome refresher and new knowledge.
a subject that gets me all wound up.
my 'work bench' is a toroidal mess.
go watch evesblog
Danke sehr für die wundervolle Arbeit und Mühe. Deine Erklärungen waren verständlicher als manch Uni-Professor. Hoffe auf weitere Videos mit deinen unmissverständlichen Erklärungen.
M Steyn . First of all, Thank you for all your time and effort I think there is allot of people out there that can appreciate it Thank you it is a excellent lesson
Awesome tutorial, I've never heard such a great explanation of inductor basics.
Please continue uploading videos!
Thanks for the amazing video. You did a really great job. I wish we could all be that helpfull towards others in many other fields. Really greatfull. You have a very good way of passing information to your viewers. Welldone, keep up the good work.
Manos.
awesome video. i now have an intuitive understanding of inductance/magnetism. thanks for taking the time to do this.
Great. Helping so many people is more than I could ever have hoped for. I guess it is time for me to finish part 6 and make people understand how voltages are induced in inductors and what hysteresis is. But it will be hard for me to keep the high standard that I have set for myself with this video.
great video.....step by step procedure is very clear.....I understood how much work and preparation is required to properly present this.....Thank you very much....I am very interested in next series - Why inductance resists current changes ... When is the next video.........
I'm working on several new videos at the moment. But it will still take a fair ammount of work, to complete them. That's teh price of quality !
This is a fantastic series. I discovered it this morning and have since gone down the rabbit hole and seen many of your videos on the channel.
Thank you very much for the time and effort spent on these. I hope to see more.
Out of curiousity do you have some sort of donation links?
tehcovmeme Hello. I just wanted to inform you that I have now added a donation link to my youtube channel. You can find the link under the "about" section of my channel. So if you're still interested in it, then please feel free to try it out :)
That's good to hear. Thanks for the update.
The Post Apocalyptic Inventor
Don't forget to tell others too.
Might i make another suggestion,within the paypal/donation settings you could enable a "recurring" micropayment option that will allow a running subcription style donation, for those who are unable to pay a large amount at once.
tehcovmeme Hey thank you for the advice. I will inform myself about these possibilities during the next days and will try to add such a function too.
i need the next parts please .. because you helped me a lot to understand swmp as i try to build one in my graduation project ... thanks for your great work and sharing it with us .
Thanks a lot, realy apreciate your work.
Super, video lighting, sound, explanation, practical experiments and ilustrations, love it :-D
Looking forward to the next episode, hope you will include something about transients, it would be most apreciated.
Greatings from Denmark.
I love this.
Highly detailed explanations and such.
I am an electrical engineering student btw.
Keep it up. :D
