Outstanding presentation Thank you very much, Professor! I appreciate it when you present us with something out of the ordinary. Nowadays, everyone sticks to the fundamentals. Continue doing what you're doing. It's fantastic!
Very nice presentation. I am a PhD student and a relatively long time follower of your channel. I am really fond of your videos. My research subject is about this filter, a few novel improvements, and a non-linear control strategy for a converter including this filter. I hope I will be publishing my results by the end of the year, maybe we may have a chat to discuss this really interesting topic and you can share your experience with me.
Hi, thank you for your kind note and for sharing the information on your research. I will be happy to read your paper when available and I am open for exchange. Are you considering active filtering? I am wondering if it is possible to combine ripple steering with active circuitry. Good luck with your research.
Thanks for publicizing this interesting filter architecture and providing the LTSPICE analysis. It seems like adding a little series resistance in with the capacitance could reduce the filter's Q and give more uniform attenuation results in the presence of up to +/- 1% changes in k. in any event, it's an interesting structure and I am looking forward to exploring its usage for band rejection in power applications. Thanks again for putting this out there!
Excellent presentation Dr Yaakov. I think it would be interesting to use such a filter in high power converters in SiC mosfet since they usually have a lot of emc issues around switching frequency. By tuning the filter accordingly, i am guessing we can achieve a better emc performance not only at switching frequency but their multiples too.
Good video. Made a bidirectional buck/boost converter once by self designed coupled inductor on an E core using copper foils. Was interesting to see the coupling coefficient dependent on the reluctance ratio between inner leg and outer leg. Due to the flux cancelling out in the middle leg, a high efficiency could be achieved when comparing to two single inductors.
Be sure to see Joe Morerro's papers (National Semiconductor). He owns many patents on this topic and has some really great paper for ripple and regulation steering. I had the opportunity to work with him a few decades ago. Really brilliant.
Dr Ben. Thankyou. Your videos have been an enormous help. Jeff
Thanks Jeff
Thank you very much Professor. The analysis is very clean and easy to understand. I always learn a lot from your videos.
Thanks
You are the best !
🙏😃

Sounds like this type of filter would be ideal for fixed frequency converters. Thank you for the video!
Thanks

Perhaps, if the losses and attenuation of notch will not make this worse.

Interesting. Thanks for sharing.

Thank you, so such a approach of buck dcdc will reduce conducted emmision

Bodos Power magazine drawings are always low resolution, unfortunately. Not sure if the printed magazine is better or not ?
I will check, I should have a copy around.
One neat thing about this method is that the extra winding does not need to use as large of wire as the main winding.
