0-1000 Volt Regulated High Voltage Power Supply
Basic operation of this circuit is similar DC to DC converter. With input from 18VAC at 800mA then converted to DC by B1 bridge rectifier. R11 work as adjuster, a twin of IRF510 as final amplifier, and a CT transformer is the last converter to provide the high voltage output.

Excellent PS, What do I need to do for increasing the output current to 3 Amps, I need a 0-1000 Variable voltage 3 amp output.
