Hi folks. Old thread, old code but beautiful code. I'm in the process of converting a square wave inverter to sine and this piece of code struck me the second...

Larger inductances, less permeable cores. Check the cores temperatures. They might saturate even without load, only with the reactive power from the capacitor.

Alright then, I think I know now what happens. You are switching at very low frequencies and the inductors have to low impendances at those frequencies. Pump up SinDivisions (xx),...
