To accurately know abnormality information, cutoff operation information, and time-series order for the information even a power converter in a set parallel configuration in which a plurality of arithmetic processors are used.
The power converter in the set parallel configuration includes: PWM rectifiers 3A, 3B and inverters 4A, 4B, in which serial connections of the rectifier 3A and the inverter 4A and the rectifier 3B and the inverter 4B are connected in parallel; a PWM rectifier side arithmetic processor 6 which performs control calculation of the PWM rectifiers; and an inverter side arithmetic processor 7 which performs control calculation of the inverters. The PWM rectifier side arithmetic processor 6 which detects that an abnormality occurs in the PWM rectifiers and the inverter side arithmetic processor 7 which detects that an abnormality occurs in the inverters are provided to send signals to each other when an abnormality is detected in either of the PWM rectifier side arithmetic processor 6 or the inverter side arithmetic processor 7.
