Abstract

This disclosure relates to a control for pins or conventional corotrons. Heretofore, a voltage multiplier network was provided for sharing a high voltage power supply between multiple discharge devices such as pins or conventional corotrons. The control disclosed herein utilizes an operational amplifier and a high voltage transistor together with a voltage quadrupler network to directly control DC current delivered to a photoconductive surface.
