ABSTRACT:
A diode, a condenser and a switching element are connected to a primary winding of a flat type transformer such as a wire type transformer. A citation energy discharged during an off-condition of the switching element, namely a reset period of the transformer, is accumulated in the condenser. An output voltage is obtained from the condenser. Two system direct current voltage output can be obtained from one transformer. Since the two system direct current voltage output can be obtained from the transformer having a pair of a primary winding and a secondary winding, the volume and the weight of the transformer can be reduced and the compact and the slim of the machine apparatus being mounted can be contributed. Making the small winding ratio of the transformer, the copper loss of the transformer can be reduced. By using MOS synchronous rectification, the loss in the circuit can be reduced. It is unnecessary to select highly the switching frequency.
