Sorry I missed that. Probably should stay off the list when I'm in a

The steady-state net charge transferred per cycle will be zero
regardless of waveform. It's a capacitor. No DC component.

No. He wants to power a 16A mill. His problem is high inrush on
startup of a DC supply. Soft-start is a reasonable way to solve it

The PSU has a quite high
