Thank you for your efforts to share and teach! It is much appreciated! Here is a little viewer feedback that you might find useful and encouraging... 1) I am a just a self-taught EE hobbyist and 2) this video covers significantly higher circuit concepts. Even so, you were able to communicate so well that I was able to follow along very easily. And, this occurring without me having watched the prior referenced video. So, bravo to you, good sir!
Dear Prof. Ben-Yaakov, Thank you very much for your videos! I would be thankful if you could advise on the two following subjects: 1. Please give a few examples of commercial controllers that exploit this method. 2. Please elaborate on the pros and cons of this method compared to the Current Mode Control (CMC). It looks like the Ripple Control is easier to design. Yet, if we want to protect the switches, we still need to measure their currents, like in the CMC. Thank you very much.
LM5164QDDARQ1 is a variation with constant on time. PCM is in general better but the ripple conrol has advantage when fast response is needed and when the input voltage range is large.
Hello Professor, my friend got the idea for the control method of a parallel resonant ZVS/ZCS SMPS with a huge dynamic range of regulation, and he tested that successfully(single-stage AC85-250V SMPS with PFC). Could you please suggest to him the next step?

Hi Professor, thanks for the valuable explanation! One question: is this voltage ripple always detectable in practice? looks like the sensing could be quite sensitive, is this right?
@@sambenyaakov Hi Professor, thanks for your reply. Do you have concern on the parastic inductance's impact? I am thinking about an output with many electrolytic capacitors. Maybe the current injection can even improve this situation?
Hello professor,May I ask for an advice I am currently final year student of king mongkut’s university of technology north bangkok studying Electronic and power electronic engineering. I Love Power elctronic and I also keen on embedded system and pcb design. I'm myself I have little to no expirence working with real engineer in this field. For that reason I'm still looking for a job as R&D in power electronic or embedded system to get to know how real engineer work and do thing.So what I want to ask for your advice is if I want to get better in working as power electronic and embedded system engineer what is your recommend and am I on the right track looking for R&D job?. Thank you professor
Hi, Indeed, the best way is to take part in design work in the industrial environment, with experience engineers from whom you can learn and grow professionally..
Hi professor, there are many attempt from literature to develop small signal model of ripple control and analyze its bode plot, is it valid to have small signal model on this kind of control?can you comment?
Good question. I am all for small signal and average models. But there is a point that one has to realize that when a system is higly nonlinar, linearization means little. We need more large signal analysis tools.

Thank you for kind note. Comments like yours keep me going.
Your videos have made power electronics much more approachable. Thank you for explaining the missing pieces from app notes
Thanks
Thank you professor. Excellent ❤👍🙏🌹
Thanks.

If he is an academician, a paper

As explained in the video you can inject it

@@vanease1 I mean to inject the ripple into the point of sampling (divider). This is explained in video
Very helpful! Thank you!
Glad it was helpful!
Wow !! I just commented few minutes back in your previous video regarding new video and it's uploaded 🎉
😊👍🙏
Very interesting ! :)
Thanks
are you Israeli?
Yes indeed
