This is the best mosfet explanation I've ever seen, much appreciated.

Best explanation I ever found so far on KZfaq, and from elsewhere (including some webinars from semiconductor manufacturers). I'll recomment your video to everybody who'd like to know more on this topic, and on my own videos if it comes the chance. Thank you for posting, greetings from the Alps.

Possibly the best explanation on the planet. Brilliant. Thank you Sir.

One of the best MOSFET driver tutorials that you can find on the internet. As usual, clips of Pro. Sam Ben-Yaakov are very practical and his explanation is intuitive and can not be clearer. Watching hours of his lectures on KZfaq saves me days on the labs. These are some of my favorites on his channels: PWM controllers (signature is peak control mode), MOSFET drivers, Ground looping, inductor/transformers. I just wonder is there any book that he has published which covers those topics, i definitely stock it up on my shelf

This is THE best MOSFET driver tutorial on the internet. Thank you professor!

This is by FAR FAR the BEST no bullshit down to earth explanation on the internet!!! Thank you thank you thank you.

Thank you Professor, I love how your videos are the perfect blend of applied engineering and theory/maths! Its very hard to find that.

Thank you Prof. Ben-Yaakov, well-explained and very thorough. Videos like this help millions of students who cannot afford expensive books and after-school institutions. You are a teacher of millions: what a big class you have Prof. Ben? Thank you for running a school without boundries and with A-class level. God bless you and your team.

Thanks from Poland! Very interesting lectures, clear manner of transmission, information beyond the basics. Something like this I was looking for.

Quality explanation. Great!! Lot of issues are addressed. Probably best on KZfaq.

Such elegance in every depicted detail can only come about through a long experience of dedicated work. Congratulations and thank you for your presentations.

Thanks for comment.

Your explanation is simple, deep and educational at the same time. It's been a week that I try to find a solution to control the mosfets of a speed variator for three-phase Asynchronous motor. A floating power supply was essential, and the methods using transformers or optocouplers did not satisfy me. You just saved my life with this IF2110, thank you so much. In addition let me congratulate you on the English used, simple and concise while in the technical field I am more used to French.

Informative, concise, well-explained... It is clear how much you really love teaching, and we all appreciate it. I am an electronics degree student and even though some of these concepts have been mentioned in class (while talking about converters) only with your explanation do I begin to understand how much there is to know about this subject. I am eager to rewatch the video with time and patience to really soak up everything you said. I would be happy if one day I would be able not only to interiorize the knowledge but to explain it half as good as you do. Thank you very much.

Thank you, Mr. Ben-Yaakov. Easy explanation. You are talented teacher!

Wow this is the best explanation on power tutorial I'm trying to build a two phase ---two three phase inverter. Thank you you cleared up so many questions i had...

That is outstanding! I’m an electronics engineer and design power circuits. I have saved many, many videos on machining and other engineering topics to learn from, but this is the first electronics video I have ever felt the desire to save for future reference. Simply superb!

ı am following you over 2 years and sir you are a really good person. because you are sharing with us amazing informations. ı respect you very much. thanks for tutorial. be safe.

Wow ‘DC restore’ , there is always some gold hidden in your videos thanks for sharing.

Thanks for taking the time to share your knowledge of power electronics Prof. Ben-Yaakov!

Very excellent explanation, professor. I learnt a lot from your video series and got a better understanding of what is really happening in power generators. Thanks again!

Best electronics channel on KZfaq by far! Thanks!

'intuitive " is the word, your reasoning is so clear it is amazing how I can follow you despite being not real electronician, merely hobbyist trying to repair laptops tvs and other ! Thank you so much

I love how you frame it from an engineering design point of view. It seems obvious now that you have said it. I'm excited to read through all your series. I hope to be able to apply this knowledge at work soon!

your video is very useful for pupil in confusion on MOSFET like me. now i am in settling my disturbance and do not afraid to observe at PCB of electronics and give advice for those who turn their face away from PCB. thank you sir !

I couldn't be more grateful for such an amazing video. Even if I am already graduated, this video helped me understand drivers better than any other lesson.

Very useful presentation. I like the methodical approach of showing the problem and then a solution. It makes everything easier and show the real engineering and design process. Now I understand a lot of nuances better.

Thank you for your detailed explanations, they are truly educational and practical. I feel like the fog has been lifted in my mind pertaining to this subject matter!

Thanks for the nice explanation. I have been testing some SiC NMOS and I prototyped a rig with some wires and terminal blocks to see how much switching frequency I can drive the mosfet to with air cooling. I have stray inductance every where of course since it is not a pcb. The circuit is a low side drive of a resistor bank, I observe a weird waveform accross Vds when with the falling edge of the pwm driver. It is not the typical ringing, it is rather a very high spike in voltage that is followed by negative voltage and then the typical ringing around the supply voltage. Snubbing is not getting rid of the first spike.

Amazing excellent course thanks for every minute of your time .... ❤

Your channel is gold, thanks Prof. Sam!

Though I am late to ur lesson but it was marvelous...as an amateur I encountered tons of problems connecting to mosfets in simple and naive methods which by accident worked but mostly either not perfect or doomed to failure....ur a teacher....but a professional one....so many thanks

Best explanation I've heard so far! Thanks for the education.

your lecture is fantastic, it's very helpful to understand power electronics. thank you, dear.

It is thorough tutorial both in theory and in practice. Thanks a lot.

Best preparation, thorough. This vidio will be on KZfaq for hundreds of year.Big salute, Thank you.

Thank you very much professor!🙏 Your video helped me a lot.

I used a form of that DC restorer circuit to develop a solid state version of a gate driver for a very large SCR that needs a many amps to turn-on quickly and reliably yet one wants that to be brief to reduce unnecessary gate power dissipation. Selection of a quality pulse capacitor that can handle that repetitive peak current turned out to be key for reliability.

You are a teacher par excellence, Professor.

Very many thanks Professor for such a prompt reply. As always the more one finds out about a situation the complex it can become. Seems likely my problem has much to do with using 6 MOSFETs in parallel & poor dynamic current sharing. Variation in Vth can result in some devices switching quicker causing others to go out of S.O.A.. Advice appears contradictory as fast switching, am told, coupling gates using low or zero series gate Rg & hard switching helps reduce this effect. Am also told that parasitic oscillation can occurr for the same reason & increasing Rg & fitting your recommended Fe bead on each gate cures. In my case looks like some Rg value between these arguments is needed. Experiment is called for. Thanks again. Dave

Very useful. Very good presentation.

Very well explained Dr. Sam

thank you very much from India.

One of the clearest explanations of this topic I've seen. Thanks for sharing

What a superb lecture, thank you so much

Very great presentation, covers every aspect about MOSFET driving. Thank you for listening to my request!

Clear and interesting explanation....Thanks a lot

One of the best videos in youtube Thank you

Excellent explanation, thank you

Wow, it still helps people like me trying to overcome the ringring of the high side MOSFET.

you are very kind human person

Great video prof. Thank you 🙏

The best tutorials on power engineering!!

Thank you Sam keep it up

Great video. Detailed explanation of gate drivers Thanks a lot

This was a very informative and well-explained video!!! Thank you sir, for the dedication u put into it!!

Excellent video. Thanks

I appreciate you more everyday.

Great explanation. Thank you for sharing your knowledge!

I've only just discovered this channel, but it looks to be a gem - a real breath of fresh air, with enough attention being paid to the underlying circuit physics to make genuinely useful derivations, as opposed to the vigorous hand-waving available on most KZfaq treatments of the material. However, I have a question: in your derivation of the Miller effect, starting from about 5:55, you seem to be claiming that the voltage across C_{gd} is V_{GS} + V_O. From your diagram, the top of C_{gd} is at V_O and the bottom is at V_{GS} - I would therefore expect the voltage across that cap. to be V_O - V_{GS} I am clearly misunderstanding something, but I can't see what it is - maybe I'm making a sign error somehow?

I think is usefull use term "critical resitance" for oscillation. Critical resitance is Rcrit = 2*sqr(L/C) which give no oscillation beatween L and C, because it gave critical aperiodic course of voltage. Thanks for great material, which take all important information in one lecture.

Your videos are the best. I, as a Master's student of Power electronics, get most of my concepts cleared on your channel. Please explain the effects of body diode in MOSFET and how this varies when we use IGBT.

Thank you very much for detailed explanation.

Thank you very much! Outstanding explanation, practical topics...

Indeed VER well explained from the first minute already! Excellent stuff, would be nice to have a PDF of this...

I really loved it....the drawings are too clean!!!

This is so good thank you very helpful

Excellent lecture series!

Hi, Sir Sam Ben Yaakov, really its your maturity in cool engineering.

Learn a lot from this video! Thank you sir!

Boa tarde! Gostaria de agradecer os ensinamentos que estou tentando em vários vídeos que você está produzindo. São os melhores. Parabéns, ótimo trabalho! Obrigado!

This is great stuff as usual. Thanks for helping remind me how my HV motor driver gate drivers behave! Best regards.

Very useful. Thank you, Professor.

Sam, Thank you for your explanation of the concerns of power mos gate driving. I did notice one circuit that was given up too quickly. That was the p and n fet totem pole gate drive that was given up on because of shoot-through. If the input gate resistor is moved from the power fet to the source of the driver p fet you get a fast turn off and a reduced turn on current which is desirable with out shoot-through. Respectfully, Ray

Thanks prof.Ben for detailed lesson on Mosfet

Fantastic video, thanks a lot, it helped me understand gate charges, it has always been very difficult for me to realy understand. Greatings from Denmark Morten

Great tutorial ! Thank you very much!

Thank you sir for the explanation

Thank you very much for sharing your knowledge in such a structured manner! I'd love to be your student at the university :)

Sir your video is very useful thanks

Excellent explanation! Very well done!

Thanks!! i like all your videos. im glad i can be your student on youtube. respect, sir!

Thankyou very much for great knowledge sharing

So interesting! Thanks for teaching.

I am delighted that I found your channel. I just subbed and I will study hard. Thank you!😁

Very helpful sir.

I want to give you a thousand of thumbups, prof!

Excellent Sir... 👍

Outstanding!

your videos are so helpful for me sir ,thank you!

Really great !

Thank you! It's very helpful!

Yes, this is interesting and helpful. Thank you.

I thought I would try to use the IRS2186 "4A" banner spec to drive 2 HY1920P MOSFETs (4 total) and it's looking like the driver will need to deliver peak 3A. Qtot=200nC, Vgs=10V, Vds=170V Although in practice it gets boiling hot! It is dissipating around 2W of power! Thanks for teaching me this!

Super video👌

thanks for this video, I think I'm going to try to use the Transformer - DC restorer - Driver Circuit as the gate driver for a non-inverting buck-boost in a Solar MPPT project

I omitted, in my question regarding fast turn-off diodes shunting MOSFET series gate resistors, to say that I do not know much about the original drive speed or frequency but I do know each Rg was 47R with no fast turn-off diode. My question really should have been is relability improved, maybe at a reduction of efficiency, by using a slower drive edges? I have attempted to comply with your recommendations with snubbers & safely limitted my device overshoot although admit I have not verified my circuit at the full 6kW. Thank you again. Dave johnson

amazing sir

Thank you!

Excellent video. Thank you.
