HV- voltage multiplier circuit confirmation needed

[Steven Dufresne]

Hi All,
I'm trying to make a new voltage multiplier board for one of my power supplies so that I can get negative HV from it instead of positive HV. I've attached a drawing of the simple changed circuit that I think will do it below but I'm not an electronics expert. Can someone who knows better tell me if I got it right? Note, I used electron flow instead of conventional current since that's the way I think.
Thanks,
Steve

PS. It's for my Hyde generator project:

It's basically a big capacitor with rotors and stator in between the plates. Previously I was using HV+ on one plate and ground on the other. I want HV+ on one plate and HV- on the other instead. I'll use separate power supplies for HV+ and HV-, both relative to ground.

Hi,
just reverse the diodes... your idea is fine but make sure you limit the output current if you just need the volts!!!

Thanks @wings and @crowclaw! And good idea re limiting the current. I'm not sure if I need just voltage but I may try that too.

With regards to the multiplier pictured, what kind of rating do those capacitors need to be?
