Abstract
A switching element is connected between a power supply and the primary winding of a transformer, and it is on-off controlled with a predetermined cycle and with a predetermined conducting period. The secondary winding of the transformer is connected to a parallel circuit of a filtering capacitor and a load via a rectifier diode and a choke coil. A closed circuit, to which the reflux current of the choke coil flows through the parallel circuit of the filtering capacitor and load, is formed by a reflux diode.
