Ok sorry im not very talentet in Curcuit stuff but... Is the Condensator not pulling the Drain under the Gate Voltage in stead of adding up the Supply and the Condensator? I realy tryed to Rap my head around it. But i cant see how it schould pull the Voltage over its supply. Bevause 2x 12 Volte parallel are still 12V just in Series they get 24V. So i think the Condensator is "Chargin Negativ" and "Pulling Charge" away from the drain to make the Voltage differenz. Caus it cant charge over its supply.

Good video, was using it to refresh my knowledge, one point, thermal runaway can be eliminated using a source resistor, so as 'I.s' increase, the voltage across the resistor increases reducing Vgs - just a form of negative feedback, can also be used on bipolars.

PS: another way, is to generate a seperate power rail above the drain voltage-for those thinking of doing this.

Most H-Bridge already have driver and cross-detection or so-called dead-time, if you need the power by using 4 (or 6 for brushless) stand-alone MOSFET's, you should not just use mcu-gpio to drive them that is for sure.

I am so glad so many people like yourself are out there, getting on youtube, and expanding their futures, while teaching. I'm an old fart, I've been working in this field more than fifty years, but you've taught me more than a thing or two, "surface mount, liquid solder, oven soldering", what's this world coming to? Very nice demonstration, thank you.

Genuinely the best explanation of MOSFETs and how to drive them I've ever seen. The only thing missing, which can trip people up, is depletion vs enhancement mode for both P and N channel

Amazing work GreatScott!, this is yet another example of a series of your invaluable electronics learning resources.

Great timing on this subject. I was planning to look into the usage of gate drivers tomorrow.

Enjoy the detail you put into your videos...even if I don't always understand what is going on. Thank you!

I love the detail you provide - I do not understand on the first viewing, but that is the strength of online, view it more than once

I am blown away of how professional this is...

Huge thanks for including your workings in the videos ... so often folk try to cover such topics and just hand-wave the selection of component values. Big takeaway... if in doubt, add more MOSFETs!

I’d love to see you discuss the consequences of using a 3.3v PWM output as provided by an ESP controller. Currently I have some designs where I’m providing a 15vdc gate driver voltage to facilitate good MOSFET switching, but that’s now a second power supply on the pcb (in addition to the 5vdc one to drive the ESP). The MOSFETs are driving 24vdc LEDs.

Very well done videos. You have a natural talent for teaching. You lay out the concepts in a logical way which makes them easy to understand. I have a formal education in electronics, but informal instruction like this through KZread is really amazing for the hobbyist without a formal education. You have earned a new subscriber. I've used plenty of MOSFETs in a variety of circuits in the past, but even professionals seldom just know how to do these things from memory. Unless you build the same circuits all the time it is often helpful to study some references before designing anything. I think videos like this are even useful for professional EEs who want to brush up on the concepts before diving into a design. I just bought a broken plasma cutter. It works just like a big off-line SMPS by rectifying the 240 VAC in to 350 VDC, then switching the 350 VDC with a variable current limit and rectifying the resulting AC to develop the 10-60A needed for cutting up to 3/4" (19 mm) steel like the proverbial hot knife through butter. On the switching board are 16 FETs arranged in four groups of four in an H-bridge. I can see two rather large torodial gate drive transformers on the board. I am looking forward to the next video to make sure the technical details of using gate drive transformers are fresh in my mind.

This is the best video you've made for months! I'm very excited about part 2.

I wish I could do more of practical, you really set good example with calculation it also helping me with theory and calculation

For some of those applications, you can use a MOSFET driver directly to drive the LED Load. The ones for example in my inverter are rated for 9 Amps and actively drive high and low, which is useful if you want to encode data on a fiber or laser diode.

So glad I came back and watched this again. Was defo worth the 2nd viewing.
