Abstract

PURPOSE:To prevent destruction of circuit elements, by breaking supply of the drive signal for commutation failure of a gate controlled switch. CONSTITUTION:The series circuit of work coil 6 and capacitor 7 and damper diode 8 are inserted in parallel between the anode and the cathode of gate controlled switch (GCS) 1. Oscillation output pulse Pt of voltage control oscillator (VCO) 9 is supplied to drive circuit 11 through AND gate 10, and the output of drive circuit 11 is supplied between the gate and the cathode of GCS 1. Output control circuit 12 is provided in connection with VCO 9, and output electric power is varied by changing the oscillation frequency of VCO 9. Detecting circuit 14 to detect a damper section from the anode voltage of GCS 1 is provided, and a positive detection pulse of the pulse width corresponding to the damper section is generated from detecting circuit 14 and is supplied to AND gate 10 through inverter 15.
