ABSTRACT:
A control circuit for a corona discharge device in which the high voltage to the corona wire is electronically controlled in response to an error voltage generated by summing a reference and a sense current. In one embodiment the sense current is proportional to the screen voltage and in another embodiment the sense current is the current to the photoconductor. In each case the sense current is isolated in a single resistor. The high voltage is adjusted by utilizing the error voltage to adjust the control voltage to the high voltage power supply.
