Abstract

PURPOSE: To stabilize output voltage and current characteristics without using any DC insulating device by providing an auxiliary winding to the secondary winding of a transformer, and converting the output thereof to DC.
CONSTITUTION: An auxiliary winding 1T is wound to a transformer 1 in tight coupling to a secondary winding 1S with sufficient insulation in terms of DC, and the output of the winding 1T is converted to DC by a rectifying and smoothing circuit 13. This DC is applied together with the reference voltage of a reference voltage power source to a differential amplifier 8, and an oscillator 9 is connected directly to a driving circuit 11. The voltage converted to DC by the circuit 13 is afloat with respect to the welding voltage of an output terminals 5 and therefore its reference potential is taken at the emitter potential of semiconductor switching elements 3A, 3B, whereby a DC insulating device is omitted.
