Abstract

PURPOSE:To stabilize output voltage by connecting positive potential from the output of an oscillator to the base of a transistor and negative potential to said base through a transistor. CONSTITUTION:The converter is oscillated through the operation of the transistor Q1, and positive voltage is generated at the integration circuit of a resistor R3 and a capacitor C4 connected to the secondary side of a transformer T1. On the other hand, DC input is rectified by means of a diode D2, and negative voltage is generated. When the DC output voltage becomes higher than predetermined voltage, a comparison circuit 3 detects the increase, the transistor Q3 is conducted, the base potential of the transistor Q2 is lowered and ON time is shortened. When the DC output voltage becomes lower than the predetermined value, ON time is prolonged, and the output voltage is stabilized.
