A constant voltage IC(3) converts the voltage into DC to drive a Hybrid IC(4) changing pulse width to generate frequency depending on input value using a PWM(Pulse Width Modulation) circuit. AC 110V passes a noise reducing filter(7) and a bridge diode(8) to be converted into DC 150V. The DC 150V is impressed to the FBT. A C_1(5) and a C_2(6) are waveform compensating electrolytic condensers. A C_6 is high temperature compensating electrolytic condenser. A variable resistor(13) changes primary impressed voltage.
