Current Transformer based Current Sense Circuit Design for Current Mode Power Supplies

[@adrienferreira4666]

Thank you Dr Seyed Ali Shirsavar, I saw such circuit in the B-G474E-DPOW1 Discovery kit from ST, in the Buck/Boost sub-system and I've always wondered why and how it works! Thank you very much for the explanation and the demo. You're a good teacher :)

Thanks, Dr. Seyed, I’m just starting in electronics and your explanation on a question that I had is very helpful . Thanks a lot for a great lesson.

Thanks Ali for your educational videos, this video like your previous videos was very informative, Questions: What modelwas the current probe? What was the model of your scope? Thanks

but if there is no hall sensor in place, how is this useful for measuring the DC component of the current? I can see it will measure the AC component of the current waveform but the DC component seems to be lost while with the sense resistor you measure the whole waveform

How to suppress the current spikes in the secondary of the current transformer I tried RC filter but the spikes are still there it effects the shape of the secondary wave form but not the spikes

So, you don't need compensation ramp, with big ratio of current transformer?

how can we sense current from lines by current transformer in simulation ?

Very helpful
