Zusammenfassung:A power conversion device includes a backup power source as a power source for a discharge controller that discharges electric charges of a capacitor, and an abnormal state in the backup power source or loads is not capable of being dealt with when power is supplied to loads from the backup power source, which makes an output voltage of the backup power source be in an abnormal state. In order to solve the problem, when an abnormality occurs in the backup power source or in loads and the abnormality is detected in power supply from the backup power source, a place where the abnormality occurs is specified. When the specified place where the abnormality occurs is a load, power supply to the load is stopped, thereby preventing the output voltage of the backup power source from being abnormal even when an abnormality occurs in part of power supply destinations.
