I have this really simple buck converter circuit but I am getting really funny results.
I tried different input voltages (12-650 V), no matter what I put, it doesn't affect the output. The output voltage amplitude changes with the change in PWM voltage amplitude. Changing the duty cycle doesn't change the Vout amplitude either. I tried different MOSFETS as well which also included SiCs, IGBTs, etc.
Been stuck at this for a few days now, any help would be greatly appreciated. Thank you.
