PROBLEM TO BE SOLVED: To provide an AC current supply apparatus that prevents excessive power load to an external AC power supply even if charging to a storage battery from an external AC power supply and use of an AC power supply socket are overlapped and minimizes power loss.SOLUTION: The AC current supply apparatus includes: a power storage means that accumulates the DC current obtained through the AC-DC conversion from the AC power supply; and an AC current output means that outputs the AC current obtained through the DC-AC current conversion from the power storage means, and supplies the AC current into the AC current output means from the AC power supply without through the power storage means, when the power is supplied from the AC power supply and the AC current output means is used. |
