Is this the BEST Voltage Converter? Trying to build a Synchronous Converter!

That: "Stay creative, and I will see you next time!" goes crazier every time. I love it!

Really interesting project. I am doing a PhD on power electronics and I have previously studied how to improve buck converters. There is a topology called "active clamp ZVS buck Converter" that besides using synchronous rectification with mosfets allows to have ZVS in the switching of the mosfets, which greatly reduces the switching losses. In addition, due to its behavior, it allows placing several modules in parallel to increase the total power without additional control, since it distributes the current automatically.

FYI, many STM32 MCUs have a PWM mode with complimentary outputs and dead state insertion -- specifically for switched mode power supplies and brushless DC motors. I didn't really understand the connection until watching this video. Thanks!

Sounds like How your GPUs/VGAs' Chipset and VRAM module voltage are supplied. A mosfet driver, Low and High Side Mosfets, A Capacitor, and an inductor/Coil. Interesting!

I dont have a more new ideas for you but I can totally say that ur are the most detailed videos I have ever seen. I keep trying to learn from ur videos.. thx for encouraging everyone.

Your videos refreshed my 4 years of Electronic study in 2 hours. Thank you very much

Great scott, sir. I know it's less likely that you read this. But I love how much clearer you explain everything steps/components now. When I was first year hs, I can't understand a thing in your videos, it's full of maths and very fast. It's just great to look at but nothing to learn from. Only your same level could understand. But since they are your same level, they couldn't also learn anything. Now that I'm getting college that I understand those videos, but still they are very fast and unclear functions of components. Now you are very much more interactive. Much more clear in explaination. And much longer videos but still direct and great written videos. I actually learn many things now. Thank you so much!

Your explanations are getting even better! I am amazed

Thank you! Really love power supply projects, explains the basics very well.

man, i love the drawings that you do. they're so... precise

Very good information on the synchronous rectifier part, it helped me to understand how it works a little bit better. Thanks for sharing.

Thanks Scott! Now I'm 'very glad' I picked a 'Synchronous Converter' for supplying my 150W pure sine inverter with the correct voltage when using two of my EGO (56VDC) batteries ... Makes for a nice, small, emergency backup and camping power unit. 10AH@56V ... 560WH. 5VDC, 12VDC and 120VAC as needed.🙂 Nice job on making one!

Also a neat observation you might like, if you look at the generalized/abstract schematics for buck and boost converters (using switch symbols instead of practical implementations, you will see that they are in fact the same. Just the port where power input and output are flipped around. You can make a buck converter, feed the voltage into the output, and use the input of the buck converter as the output to turn it into a boost converter! This does not take into account any practical aspects of the controller or MOSFET drive but it should be possible!

I love all your videos. Thanks so much for doing these!

Thanks for explaining! I've done a few integrated buck conversion designs in my circuits, and I'm really only familiar with the diode type topology, that explanation opened my eyes

Great video as always 👍😀 One little trick when soldering SMDs: put the required amount of tin on the pad, and 'cut it off with the solding-tip' and then drive it with solding tip to both the pad and the compont-lead. It is faster this way, and you have more control of the amount of solder on the compont/pad. And do the same on the first pad too. You can adjust the amount of tin, by cutting the length of the tin, or using a thinner tin on SMD😀 Thanks for sharing your great walkthrough of the electronic wonders of the world 👍😀

Scott, this is one of the best videos about DC-DC converters i've seen!!! Such a good explanation with graphs and examples. I Appreciate your great work put in this video! Will be interested in next topic: efficient BOOST converters and are they possible?

After adding a feedback system. I hope you can go forward and talk about isolated dc to dc converters. The bridge configurations. Zvs. Zcs and phase shifted pwm are very interesting topics and I would love to see what you come up with as a real circuit because I could only get the design due to lack of a workshop of any sort. But yes please a feedback system first. You have a way of making these topics simple to understand to start out

Relay like you explanations and the written diagrams you do that go with them. I'm out of the mechanical space and you make this so clear Tks Will

I love that GreatScott finally uses ferrules in his projects! Upgrade due to last video :D
