Dear professor, i really appreciate your commitment to teach at your old age!! I still remember watching your videos to understand power factor corrector and it's control circuits a few years ago (2016) when i was working as a power electronics engineer. Your videos helped me to understand how my circuit design was working internally. You videos are one of the best resources of PE. I have recommended your channel to my friends. Now i have switched to machine learning and it's applications to finance because of the latest trend. I am forever grateful for your explanations!! Thank you dear professor. May you live long and continue to be a blessing. 🎉 Shalom. Am yisrael chai!
Thank you for the warm words. I appreciate it very much. Comments like yours keep me going. Sorry for losing you to AI. I am trying to harness AI to power electronics. Best wishes for a successful transition. Am Israel chai and and shows it strength.
Dr. Ben-Yaakov, if you remember I had that comment on FlyBuck below your piggyback Buck vid🤣🤣 We used Flyback with primary control for our 10-kV SiC gate drive power supply and the CM noise of device switching interfered the Flyback feedback and caused faults frequently. Finally we changed to FlyBuck and the problems are gone.
@@sambenyaakov That indeed would work in the case, with a higher current version driver, but the transformers were encapsulated and unable to be changed to center-tapped 🤣
When I first heard the name "Fly-Buck" some years ago, I thought TI was implying that it's very similar to a flyback topology, and never really thought too hard about it. When I see now that it's really more like a forward topology, and the energy flow is really not like a flyback. I haven't read TI's paper yet, but what is TI claiming the main advantage of the fly-buck is over a flyback (aside from allegedly smaller magnetics?)? Is it the fact that it allows for primary-side regulation? Maybe that it can be done cheaper/simpler than a flyback? Easier control loop tuning? Interested in what you think on this. I've been a viewer for several years, excellent video as always! - Thanks
Thanks for comment and input. Except for the case that primary side control of a Flyback is troublesome (very high common mode noise ) Flyback is in my opinion better. But if a stable low voltages is available then ua-cam.com/video/y2U7eLfDtl0/v-deo.html might be the best

Professor Sam. I always appreciate your fine analysis videos.
Glad to hear it! Thanks

You got me there. Forgot your comment. If you have a stable low voltage, I would prefer ua-cam.com/video/y2U7eLfDtl0/v-deo.html over Fly-Buck

Have you done a quick analysis of Dr. Slobodan Ćuk’s Hybrid Switching Converter?
have you seen ua-cam.com/video/ftY6-q0PsGE/v-deo.html
LTC has been doing primary sensing of isolated outputs for decades, no?
Indeed
Would the fly-buck better accommodate larger input to output ratios?
There might be a leakage inductance problem. I would prefer ua-cam.com/video/y2U7eLfDtl0/v-deo.html
missed an opportunity to call it a Piggybuck
Great👍I am going to adopt it! OK if I will give credit to Jontylewis or let me know your exact name?
@@sambenyaakov haha yes its Jonty Lewis
Wow food came out of the oven😅😅 ...
👍
Flyback vs. Flyback 🤣🤯
