a high voltage power supply includes a current source that provides a continuous current signal , and a switching circuit that includes a plurality of switching elements . the switching circuit is responsive to the continuous current signal , and provides an alternating current signal . the power supply also includes a multiplier - rectifier circuit with at least one loading inductor , and having an input responsive to said alternating current signal to provide a rectified output signal . the switching circuit may be configured and arranged as an h - bridge circuit . the input of the multiplier - rectifier circuit is short circuited every half cycle of the alternating current signal during the transition from positive to negative current flow .
