A power converter converts DC power supplied from a first DC power supply and a second DC power supply into AC power and supplies the AC power to a load. The power converter includes a protection circuit for allowing a charging current, which is possibly to flow from the first DC power supply and the second DC power supply to a first snubber capacitor or a second snubber capacitor, to flow to another current path, when a voltage applied to the first snubber capacitor becomes a predetermined value or more or when a voltage applied to the second snubber capacitor becomes a predetermined value or more.
