Abstract

PURPOSE:To improve the workability in the production of the flyback transformer and reduce the cost drastically by simultaneously obtaining a plurality of DC power voltages varied in the level from one winding of the flyback transformer. CONSTITUTION:A flyback pulse from a power supply winding L1 provided on a flyback transformer FBT is rectified and smoothed with a diode D1 and a capacitor C1 to yield a relatively lower DC power supply voltage +B1. In addition, this flyback pulse is applied to the series resonance circuit comprising a coil L2 and a capacitor C2, and the resonance pulse thus obtained is rectified and smoothed with a diode D2 and a capacitor C3 to yield a relativey high DC power supply voltage +B2. In this manner, two kinds of DC power supply voltages varied in the level can be obtained without windings otherewise separately provided on the flyback transformer for supplying power.
