ABSTRACT:
A high voltage power supply current regulator includes at least one high voltage rectifier diode having a plurality of pn junctions, said diode being adapted to be connected between a high voltage power supply whose current is to be regulated and a load such that the diode is reverse biased. A control circuit, operating at a voltage which is relatively low compared with the power supply voltage, controls the reverse current through the diode to the load. The reverse current constitutes the load current. The control circuit includes a light source for illuminating the pn junctions of the diode with a predetermined flux of photons, the reverse current through the diode being a function of the photon flux on the diode junctions.
