摘要： PROBLEM TO BE SOLVED: To swiftly synchronize a power conversion device after restoration of a commercial alternating-current power supply. SOLUTION: A phase-locked control circuit 10 exercises control and performs arithmetic operation in order to match the operating frequency of current commands of a power conversion device (converter) 3 which the frequency of an alternating-current power supply. In this phase-locked control circuit 10, the proportional and integral (PI) control operation system of a frequency control circuit 14 is changed by means of a switching signal from a circuit 13 which detects failure and restoration of the alternating-current power supply 1. When an anomaly of the power supply such as instantaneous power failure or power failure occurs, integrating operation is stopped. When the power supply is restored, the integrating operation is restarted. Since the operating frequency does not largely deviate during the period of an anomaly, the synchronization of the power conversion device with the commercial alternating-current power supply is realized in a short time after the power supply is restored. If the power conversion device 3 is a converter, as shown in the figure, operation with the power factor 1 of input current is swiftly achieved. If the power conversion device is an inverter, stable power is immediately supplied to a load.
