Subject: Voltage doubler, for capacitor charging

Hello All,

 

I have a 15/120 (dual) NST power supply. I like this circuit and think it
would be a good place to get my $200 worth of the Maxwell .03uf/30kv  caps.
The final cap would be an MMC to reach .015uf 4x input rating. I have 400K
in series with the charging circuit which will limit the current demand to
.11a something @ ~45 KV

 

The catch is the grounded output of the NST. Could I run the NST's floating
or will that stress the windings?   And then there is neutral. any ideas
anyone. Everything else will be at ground. Caps other PS etc. I don't want
to stress these NST's as I bought then new and know there history. Although
I would like to use them! A Dry 5KVA Potential took them out of service on
my 8" coil which is going through metamorphosis.

 

Thanks,

Jim Mora
