Abstract

PURPOSE:To improve the stability of output power by providing a detecting portion for detecting the fluctuations of power elements and a operation controlling circuit for controlling a transistor by a detection signal from the detecting portion. CONSTITUTION:The fluctuations of an output current is detected by a detection coil 14, and a detected signal is sent to a diode 17 after it has been converted into a smooth DC current by a rectifier circuit 16 and a capacitor 19. If the signal from the diode 17 becomes lower than the standard voltage of a constant-voltage diode 23, the transistor 11 reduces the base current of power transistors 6 and 7. Thus the oscillating power caused by the power transistors 6 and 7 is held down, and the collector voltage is reduced, so that the output power on the side of output load circuit becomes constant.
