POWER ADJUSTMENT DEVICE AND POWER ADJUSTMENT CONTROL PROGRAM

WIPO Patent Application WO/2023/195078

A1

Provided is a power adjustment device for three-phase six-arm which controls, via phase control, the supply of power with respect to a load from a three-phase AC power source, said power adjustment device being capable of being used also for single phase, three-phase three-arm, etc.　A power adjustment device 1 comprises: a power source waveform acquisition unit 12 which acquires phase information of a three-phase AC power source; AC control circuits 13A-C to which a thyristor is connected in anti-parallel; and a control unit 11 which, in a three-phase six-arm control mode, outputs a trigger signal based on a three-phase six-arm trigger angle and the phase information with respect to the thyristor compatible with the polarity of the phase information, which, in a single phase control mode, outputs a trigger signal based on a single phase trigger angle and the phase information with respect to the thyristor compatible with the polarity of the phase information, and which, in a three-phase three-arm control mode, outputs a trigger signal based on a three-phase three-arm trigger angle and the phase information with respect to the thyristor compatible with the polarity of the phase information.
