ABSTRACT:
A single-ended switching circuit is constituted by a primary winding of a transformer, a switching circuit connected between the primary winding and a DC power supply and on-off operated with a predetermined cycle and also with a predetermined "on" period and a resonance capacitor connected in parallel with the primary winding. A magnetic amplifier, a rectifying element and a choke coil are connected in series between a secondary side circuit of the transformer and the load. The magnetic amplifier includes a saturable reactor which is held saturated during a half cycle of the voltage induced in a secondary winding of the transformer and remains unsaturated during the other half cycle of the voltage.
