ABSTRACT:
A high voltage power supply system particularly adapted for rapid switching of high voltage applied to an anode of a beam penetration color cathode-ray tube. Energy for making the rapid transition between voltage levels is stored in two energy storage inductors, one for upward transitions and the other for downward transitions. When it is desired to change the voltage applied to the cathode-ray tube, the appropriate one of the storage inductors is coupled through a controlled switch to the anode causing the voltage applied to the anode to change at a rapid rate. The voltage rises until the desired voltage level corresponding to a desired output color is reached at which time the switch is turned off and the storage inductor recharged. A tracking high voltage supply maintains the anode at the predetermined voltage level once that level has been reached. Gain compensation is applied to the deflection amplifiers within the system so that patterns displayed upon the cathode-ray tube have a constant size independent of the voltage applied to the final anode of the tube.
