복수의 전원 장치의 교류 전류의 위상을 동기시키는 동기 시스템은, 규정의 주기의 동기 신호를 출력하는 마스터 유닛을 구비하고, 각 전원 장치는, 급전선에 교류 전류를 공급하는 전원 회로와, 동기 신호를 수신하여 전원 회로를 제어하는 전원 제어부(52)를 구비하고, 전원 제어부(52)는, 수신한 동기 신호로부터 규정의 지연 시간 Td만큼 지연시킨 위상에 대하여, 마스터 유닛으로부터 상기 전원 제어부까지의 동기 신호의 전송 소요 시간에 따른 시간 Ta만큼 진행시킨 조정 후 위상을 연산하고, 교류 전류의 위상을 조정 후 위상에 동기시키도록 전원 회로를 제어한다.

    A synchronization system for synchronizing phases of alternating currents supplied from a plurality of power supply devices includes a master unit that outputs a synchronization signal having a predetermined period. Each power supply device includes: a power supply circuit that supplies an alternating current to a power feeding line; and a power supply control unit that receives the synchronization signal and controls the power supply circuit. The power supply control unit calculates an adjusted phase by delaying a phase of the received synchronization signal by an amount corresponding to a prescribed delay time and advancing the delayed phase by an amount corresponding to a time required to transmit the synchronization signal from the master unit to the power supply control unit, and controls the power supply circuit in such as manner as to synchronize the phase of the alternating current with the adjusted phase.
