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 KZread 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

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.

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.

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.

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

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

Good point if you want an symmetrical drive. In fact you can put two resistors in series between the drains of the drive FETs and connect the gate of power transistor to midpoint.

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 KZread 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?
@sambenyaakov

Thanks for comment. This is indeed confusing. Look at this this way: Looking from the gate, Cgd was initially charge to -Vo, and then charge to Vgs. So the total charge needed is (Vo+Vgs)Cgd
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
