Inductor saturation current
I'm trying to determine an inductor's saturation current, I use a PWM with a gate driver (TLP250) and a 0.4Ω sense resistor at the source which I probe across to capture the current waveform.
I ...

Sign conventions of inductors in circuit analysis
Here's what I know about inductors:
As per Lenz's law, inductors sort of maintain the direction of current passing through an inductor. So whenever there is an interruption on the source from which ...
