Posted to www.diyPhysics.com:d.i.y. 250 kV High Voltage DC Power Supply with Neat Trick for Switching Polarity

diy 300 kVDC high voltage power supply by David Prutchi PhD www.diyPhysics.comI just posted at www.diyPhysics.com detailed instructions on the construction of a 250 kV DC high-voltage power supply.  Although my hack for switching the polarity (referenced to ground) is simple, I am very surprised that I’ve never seen it elsewhere!

The hack consists of adding one more capacitor to the Cockroft-Walton multiplier so that it can be used to produce either a positive or a negative output referenced to ground.  The post is at:

UPDATE 2/10/2012: Please see the following two posts for additional information on building the resonant transformer driver, as well as on winding the primary for the flyback transformer:
