A power conversion apparatus includes an inverter for converting DC power to AC power for supply to a load, a converter for converting AC power from an AC power supply to DC power for supply to the inverter, a DC voltage converter for converting a voltage value of power stored in a storage battery to supply DC power from the storage battery to the inverter when power supply from the AC power supply is faulty, and a filter including a reactor and a capacitor, for removing harmonics generated by the inverter. The inverter includes a three-level circuit which is a multi-level circuit. |
