I used to make a living selling capacitors for single stage charge pump they were tagged with the name voltage doubler.

I'm building a 10 stage charge pump using 400wvdc capacitors rated at 22uf. Running this pump from 220 VAC mains it's taking 3 capacitors for each stage. Minus losses I should be getting around 3,300 vdc using a half bridge from the split 220VAC mains here in the USA.

Although google is my friend I can't find much about charge pumps I've had experience building ladder multipliers
I'm just hoping that the 1kPIV diodes will hold up to the task, they are high speed 30amp surge.
