路。In a phase control circuit of a three-phase mixed bridge converter that performs phase control of a three-phase thyristor, a synchronization detection circuit detects phase voltage from a power supply, and the phase voltage detected by the synchronization detection circuit is synchronized with the line voltage of the power supply. A waveform shaping circuit that shapes the voltage detected by the filter circuit into a rectangular wave, and a subsequent logic circuit that receives the output of the waveform shaping circuit as an input. Of the positive and negative outputs of the waveform shaping circuit, the negative output signal inputs the negative output signal of the next phase waveform shaping circuit, and the negative output signal inputs the negative output signal of the next phase waveform shaping circuit. A phase control circuit for a three-phase AC-DC converter, characterized in that the control range is configured to be controllable over a synchronization range of 180 degrees.
