PURPOSE:To contrive the reduction of the fluctuation of output voltage, the reduction of the heat generation of a transformer, or the like, by connecting a bridge type full wave rectification circuit to the second winding of an insulating converter transformer. CONSTITUTION:A condenser 61 is connected to one end of the first winding 13B on the second side of a transformer 13 and to an intermediate tap, and the one end and the intermediate tap are connected to a bridge type full wave rectification circuit 60b'. As the result, a winding N2 is always used, and between the winding N2 and the resonance condenser 61, high-frequency oscillation current does not flow. Accordingly, ringing component is not generated on AC output voltage eo obtainable from the space between one end of the winding 13b and the intermediate tap. Besides, the high-frequency oscillation current does not flow to the winding N2 of the transformer 13, and so the high-frequency loss of the winding is reduced, and heat generation is reduced. |
