Rich,
Your correct! I figured the diodes you were using were series strings as most
use. You would need to use something similar to what you have. Good practice is
to use a capacitor with a voltage rating of at least 1-1/2 to 2 times the
operating voltage if possible.
Best,
Will

Hi Will,
I did not make my self clear, I only have 4 diodes in the set up , in a bridge
and that way there is full PIV voltage across each rectifier. I do not know it
they would help but a
1.5-2Kv would not work with up to 4200v ac being able to be sent to the bridge.

Rich,
You wouldn't need 10 kV capacitors there as the HV is divided equally across
the rectifiers. If there's say 1 kV across each, you can use a 1.5-2 kV ceramic
disc capacitor say at .01 uF (10,000 pF). You dont need any so-called
"balancing resistors" as they can cause more harm than good to the rectifiers.
Hope this helps.
Best,
Will
