Zusammenfassung:A charging voltage of the capacitor of the phase voltage of three phase voltage is compared with the thyristor calling apparatus of the three-phase rectifier. The power consumption can be reduced by generating the trigger voltage according to the comparison result. The rectifier(200) is the signal rectifying three phase voltage with a plurality of diodes and plurality of thyristors and is rectified with the capacitor for smoothing flat and wide. The initial charge part(210) rectifies one phase voltage among three phase voltages and is flat and wide with the capacitor for smoothing. The phase voltage detection unit(300) generates the trigger control signal compared to the reference voltage which is three phase voltage set up in advance. The thyristor driving part(220) triggers a plurality of thyristors is According to the trigger control signal generated by the phase voltage detection unit.
