PROBLEM TO BE SOLVED: To provide a highly reliable parallel operation controller for inverters by decreasing the number of crossovers between respective inverters, and making the maintenance and inspection easy. SOLUTION: Inverter control units 10A and 10B for controlling inverters 1a and 1b are constituted of voltage detecting circuits 5a and 5b, current detecting circuits 7a and 7b, operating circuits 8a and 8b for detecting the assigned currents of the respective inverters and inverter control circuits 9a and 9b. The currents shared by the respective inverters 1a and 1b are computed by the operating circuits 8a and 8b. |
