Abstract
The high voltage regulator employs a field effect transistor (FET) amplifier and a shielded wide band frequency compensated RC voltage divider. The device comprises a FET amplifier used as a current source in a 20 KV power supply. The negative output of the supply is sensed by the voltage divider consisting of two resistors in parallel with two capacitors for frequency compensation. The voltage divider output is applied to the non-inverting input of an operational amplifier whose reference is set to affect the linear operation of an inverting operational amplifier. In the voltage divider, a variable high voltage quartz glass piston capacitor is used to set the RC product of the high level arm equal to that of the low level arm.
