Abstract

PURPOSE:To realize a simple constitution of circuit, by detecting the current corresponding to the field current at the AC side of a thyristor circuit and setting the detected voltage in a single direction regardless of the polarity of the field current. CONSTITUTION:A comparator which supplies the ignition pulse to thyristor bridge circuits THa and THf connected in adversely parallel to an AC power supply, a phase shifter and phase shift control circuits IPSa and IPSf are provided. In addition, an input polarity deciding circuit HYS that prevents the input of the ignition pulse of either one of the phase shift control circuits to a tyristor circuit is used along with a switching circuit comprising a minor current detecting circuit SCC and a logical circuit LGC, a current transformer CTfa that detects the AC side current of the thyristor bridge circuit and a rectifying circuit that rectifies the output of the trasformer CTfa.
