PURPOSE:To control an output voltage by a simple configuration by composing rectifying means in combination of a plurality of rectifiers and a capacitor, and controlling a current flowed to the capacitor. CONSTITUTION:A plurality of diodes D1-D8 are connected in series between the midtap and the output terminal (o) of the seconary winding n2 of a transformer T, and capacitors C1-C8 are connected between one terminal of the secondary winding n2 and the prescribed connecting point of the diodes D1-D8. The voltage of the output terminal (o) is detected by resistors R1, R2 and a differential amplifier OP, a transistor Q is controlled by the detection output to control a current flowed to the capacitor C4. |
