機用モータの駆動回路。 When full-wave driving an induction motor with an extremely small current using a triax, in order to reduce the gate current and achieve stable triax firing, the gate current at the zero-crossing phase of the load current waveform is maximized. A fan motor drive circuit equipped with a tri-ac trigger pulse generation circuit that controls the gate current to gradually decrease as the phase advances or lags.
