Thanks professor. We use to current share two 500A 5V power supplies in an array processor product. On the larger product, the main data cage used three 500A 5V supplies. Early 1980's era.

Thanks for a very informative video as usual. Do you have any thoughts about directly connecting the current sense capacitor to sense+\- terminals? Converters that do direct resistive sensing have a built in diffamp which could be placed at your nodes S1 and S2, but I’m not sure if that would work in practice. I’m going to try it in a simulation but don’t trust it because I haven’t seen that sensing technique before. Also, how sensitive is the RC to RL matching to tolerance in practice? With 10%+ process variation in L,C and DCR before variations due to temperature and load I foresee sensing degradation or inaccuracy but I don’t know enough to make a determination. Thanks in advance for any help. You’ve already done more than I can ask!

The internal amp will not do. The RL mismatch does not affect the dc value only the AC components.

Thank you professor! Interesting topic. However, one thing confused me. How is it possible to have circulating currents between power supplies output capacitors if there are ideal diodes in series with each output 24:40 ?

@sambenyaakov 2 ай бұрын

The diodes carry DC current🙂 so the superimposed ripple can go both directions.

Thank you very much. What topology would you recommend for low current (up to 600mA), multi and isolated output dc to dc converter?

More requirement details are necessary. Interlaced flybacks come to mind but it might not be the most appropriate.

What power level?

@sambenyaakov 2 ай бұрын

So its up to 10W per unit . Are you looking for onePS with multiple outputs?The most important issue for the musical environment is noise consideration.

@_-Skeptic-_ 2 ай бұрын

@@sambenyaakov It supplies low power but few outputs may supply 4W. Yes I'm looking to build it one unit with multiple outputs. You are correct about noise, and that's why I'm looking for isolated outputs. Thanks for your reply.

@@_-Skeptic-_ I think that a soft switched flyback preferably with active clamp running at a frequency above 100K will do.

@@sambenyaakov Thank you sir ...could you please make a video on current mode control modelling of your switch inductance model and vorperian pwm switch model ,and then Ridley model ,after that Erickson model in Ltspice to get clear understanding of different models
