Hi Guy

I note on many circuits they use at least 3.3 time the rms
voltage for PIV. Ex.: 400 PIV for 120 V rms. If you respect the
same ratio for 15 KV you need 50 KV PIV. For the the design of my
mot doubler ps in a special configuration were each leg of the
bridge see only 1X the tension I use 20 KV PIV for 2 MOT ( 5 KV
rms ) 4 time.
