Abstract

PURPOSE:To keep constant the output voltage value regardless of an input voltage side by connecting a high frequency inverter to a pulsating power source wherein the secondary side of an output transformer is connected to a load through an impedance element. CONSTITUTION:A pulsating power source 7 is formed by rectifying an AC voltage 8. The DC auxiliary power source of a capacitor 11 is connected to the output terminal of the pulsating power source and a high-frequency generating device 1 varying oscillating frequencies is also connected to the output terminal. A load 6 is connected to the secondary side 42 of an output transformer 4 through an impedance element 5. The output in a voltage detecting circuit 15 is supplied to a modulating device 14 to modulate the frequency of the output signal in accordance with the magnitude of the output 15. Therefore, the modulating signal is given to the transistors 2, 3 in an inverter 1 to increase the frequency during a pulsating period and to suppress the pulsating component through the inductance 5.
