MarkRh, yes you are right. The addition of some capacitance might be needed to smooth out the wave to make it more sine-like. But we don’t know the exact form this wave will be. Maybe it will approximate a half sine wave already. And of course every circuit or grid has some capacitance anyway, every element does. But this appeals to my minimalistic nature. Might not need any transformers either. Just size the coils appropriately. One thing that will definitely be needed is good switches. Better than any in existence today.
