<p>A high voltage power supply unit employs a control circuit for controlling the output voltage provided by way of a rectifier cascade. A highly ohmic resistance and a potentiometer having a movable tap are serially connected between a tap of the rectifier cascade and ground. The movable tap is connected to a difference amplifier by way of an emitter follower circuit and the difference amplifier is connected to control a high voltage generator which feeds the rectifier cascade. A power stage, in the form of a Darlington circuit, is interposed between the difference amplifier and the high voltage generator to provide a sufficiently high load current supply for the high voltage generator.</p> |
