Hi, I haven't read the whole post but I was interested. I saw you were talking frenquency vs inducter size.

I wanted to say I'm in embedded by profession, so if you have specific needs I might be able to help. I have one of my toy with a 32 bit IC running 2 pwm at 5000hz.

Just saying it's no problem, and switching frequency is limited by the mosfet's turn off time.

I'm starting work on a 3ph open source drive for 3ph induction motors to prepare for my build. So I might as well think of the chargers now since the motor has useful coils in it.

Let me know if you are covered on the uC side

keep up the good work
