PURPOSE: To eliminate the problem of unstable operation and abnormal operation of a series-diode-type single-phase parallel inverter circuit where a diode for preventing discharge is provided at a parallel inverter circuit using a thyristor. CONSTITUTION: A resistor 15 and counter-flow prevention diodes 13 and 14 are provided from a power supply where clamp diodes 11 and 12 are provided at both terminals of the primary coil winding of a transformer. |
