ABSTRACT:
A high-voltage power source apparatus with a simple construction which outputs a voltage by overlapping a DC voltage with an AC voltage. An alternating current (AC) voltage generator generates an AC voltage and outputs the AC voltage to a secondary coil of a transformer. The AC voltage and the DC voltage are developed and simultaneously overlapped from a common secondary coil of the transformer. Thus, separate AC and DC voltage generators are not necessary to produce the overlapped voltage, simplifying construction. The DC portion of the overlapped voltage may be regulated by feeding back a sample of the output voltage to a control circuit which compares the feedback with a reference and regulates the DC portion accordingly. A plurality of the overlapped voltage circuits may be operated in parallel from a single secondary coil of the transformer.
