ABSTRACT:
A high voltage power supply having a low voltage input comprising a transformer having a primary winding, an input switching means coupled to the primary, first and second groups of secondary windings each of which are sub-divided into a plurality of component windings, and voltage converters coupled to each of the component windings for producing series output voltages of opposite polarities across the groups of secondary windings. First and second output switching means alternately switch the series output voltages to provide an intermediate voltage at a common point which is the input of a diode capacitor multiplier circuit thereby producing at its output a high voltage output.
