ABSTRACT:
An alternating current input to direct current output power supply providing a regulated constant voltage output or constant current output and incorporating a switching-mode regulating element. Regulation is primarily obtained by means of a bi-directional switching element operated at a relatively low voltage, and the alternating current voltage output from the switching element and an associated power transformer is applied to a rectifying voltage multiplier to produce a high voltage output. The voltage multiplier is subject to receiving an unbalanced potential, thereby imposing a dc off-set potential onto the switching element to cause instability in the potential at the power supply output. A correcting circuit is provided to eliminate the effect of the dc off-set potential on the switching element.
