Part 2: ukposts.info/have/v-deo/emd2paidaYNeqqs.html

If you made a full blown course of how to get started in constructing technology I’d pay for it. I love these videos would love to learn the basics so I could do projects like this.

What can I say except give him an award.

The slowly blackening tip of the yellow highlighter gives me flashbacks to college.

It bothers me that you always scrub the highlighter until it smears. Sorry, I couldn't hold it back any longer.

Another reason to use MOSFET driver: cross-conduction prevention that could prevent your Metal Oxide Silicon Field Effect Transistor into becoming Magically Obliterated, Smoke n' Fire Emitting Transistor in a bridge configuration.

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.

If you had 100 videos about driving MOSFET gates, I would probably binge what all of them today. This is great, thank you.

"The *field* of power electronics" IC what you did there Scott :) Edit: Damn, thread ended. Was hoping we'd see more electronics puns.

Dude you just resumed my B.S. Electrical Engineerging thesis on like 13 minutes. WTF Just awesome.

13:15 "But, of cousre, you don't know everything yet" It's me, in every aspect of my life. Especially when I think I know what I'm doing.

This is exactly what I was looking for. Really Great scott!!

Wonderful Video! I didn't know about mosfet drivers before this video but now I know what to do with them, Thanks!

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

You know what, there is something therapeutic and calming about the way you speak. I've been subscribed for years and just had a moment.

I have an exam on mosfets in two days. You have no idea how much this helped me

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

I started viewing your video nearly 4 years ago when I didnt knew anything about electronics and now I know things about electronics still I am enjoying how you explain

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

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 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

Happy new years, greatscott. Thanks for bringing us all along! I appreciate you!

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

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

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 UKposts 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.

The world's best teacher

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.

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.

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

Wieviel Arbeit in dem Video steckt. Krass. Mega, dass du das machst! Bin von Anfang an dabei ;)

This video helped me solve a problem on a product design that came from an outsourced electronics engineer.

I never understand your vdos (except a few), but I appreciate your knowledge!! Hats off!!

Great video!! Love the new music. I appreciate the consistency and quality of your videos too. Keep em coming!!!

THANK YOU!!! I've been wondering this for years but always forgot to look into it!

Very Nice and informative video greatscott! These are an absolute gem for engineering students! And they help tremendously in making projects. Thank you for sharing your knowledge with us!

I have no idea what you're talking about, but I do like your videos. Job well done...

Thank you for the video scott. I was researching bootstrapping capacitors/mosfet gate driver ICs a while back

this is very informative Mr. Scott. Really appreciate you taking the time to explain the various pros and cons.

Really like your in-depth videos on subjects like this one. Saves me lots of time wondering why the magic smoke escaped from my MOSFETs ;-). Looking forward to part 2!

Thanks so much for your videos. I am a fan. Working my way towards PWM treadmill motor driver and this might help. Waiting for Part 2!

Your ability to deMystify some aspects of electronic engineering is of great credit to you, You have helped me so very much as a "Mature" student (I am 62 and still learning.) Many thanks and keep up the good work !!

Great video! There were a few things I was missing apparently when I drive MOSFETS. Thanks for the information!

Hey you got Würth as a sponsor, that is a good call from them! I certainly will check their products out!

I couldn't understand half of it ... but got the gist. Can't wait for Part II to hit that Like again!

Great, can't wait for part 2 Scott. Thank you.

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

Electroboom is uploading frequently and great Scott too

You deliver the right video at right time......

Great video. I have been using MOSFET drivers in my designs for quite some time now, without really knowing (or caring, tbh) about their inner working. Thanks to you, I can now make better component selections and designs. :)

Very clear content. Informative for the beginners. Keep going.

A short summary at the end of such highly information dense video would be great! Keep up the awesome work!

i've been always confused with the term bootstrapping, now you explained it clearly with the floating ground. great video as always sir!

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

I've built various circuits based on MOSFETs but all the time Optocoupler based circuits works best for me and also would love to share that it's the only cheap, hassle-free and efficient way to drive the MOSFETs 😄

great explanation video best I've seen, and you've surveyed all the major issues one is confronted with using MOSFET's

I enjoy your videos and especially your knowledge and presentation. Thank you

Absolutely amazing tutorial !

Thanks for sharing good electronic knowledge with us.. GreatScott👍👍

Thank you, I was just about to start working on a Tesla coil project and now I know why some designs use mosfet drives and some don’t.

Genau dieses Video hat uns am Samstag in unserer Miltenbecher-AG gefehlt😅 da wussten wir nicht, wie wir unseren Motor steuern sollen...👌

Long time waited, great explanation thank you for doing such a good job.

Great explanation ! Short and sufficient.

Great breakdown of one of the world's most popular devices and circuitry. This is used in practically every switch mode power supply out there, including laptop power supplies and desktop PC power supplies, just to name a few. Power electronics including switch mode power circuits will become even more popular with electrification of vehicles. Let's all get ready for dangerous high voltage digital circuits! Yes!

Gosh, I've blown up a lot of components learning about FETs. There's a lot to get your head around. It gets even more exciting when you have inductive loads. Gate drivers and bridges definitely are very useful.

Great walkthrough 👍 Of the adventure of the MOSFET. Thanks for sharing your knowledge 👍🙂

Good Stuff! Looking forward to part 2!

Getting a real Marco Reps vibe here! Great stuff, thank you!!!

Comme "Gadget Reboot" des vidéos super claires jusqu'au fond du détail 👍

Thanks for the very useful information

He explain way better then my lecture in school a thousand thumb up for u Scott.

Great Scott is truly Great!

Excellent video and great explanations. Thank you really much for sharing all of these.

You are really Great,mr.Scott! thank you for the video.

One of your best videos!

You truly are great Scott, cause this video was great!

Finally the video we have all been waiting for

Have a wonderfull chrismas and a happy newyear Great Scout🎉

Great videos as always! Danke für die tolle Videos, ich lerne viel!

Cant wait to see the next part, already knew everything in this video but I'm very curious about the gate drive transformer

dude awesome! also ur handwriting is a gem!

As always great content, good job great scott

thanks for this! ready for the second part!!!

why is it that i enjoy the pictures you draw as much as the content?

Please tell me I'm not the only one who lmao at needing the breakout board. "It only comes in smd." 10:20 PogChamp on getting it down to 70 ns.

Good introduction to driving FETs. Thanks

I work in a start-up environment where new engineers think I over complicate stuff, without properly looking into specifications. Your video will be useful for me to pass them to get educated

Wow awesome. So concise and understandable.

Yey! Another great video! Watching from state below yours! (Czech Republic)

great explanation sir. now i can uderstand mosfet more

Really a great video...very helpful...Thank you GreatScott

This video Could have helped me a lot in my university project. I remember i faced issues just because i wasn't using a gate driver. That time electronoobs video on boost convertor helped me to figure out the issue

Love this power electronics videos! Thanks!

Finally some different sponser!!😂

I'm really looking forward to part two in the serious :)

Best video yet.

You are bringin' me good ideas to make something

Thanks for telling... Helped me a lot

This was exactly the video I needed! Thanks :)

your videos are extremely informative. thank you
