摘要：
A power conversion unit (50) includes an AC/DC converter (51) converting alternating-current power supplied from an AC power supply (2) into direct-current power to charge a high-voltage battery (30) with the direct-current power and a step-down DC/DC converter (52) generating an intermediate voltage (Vm) provided by stepping down a voltage of direct-current power supplied from the high-voltage battery (30). A constant-voltage DC/DC converter (60) outputs, to a low-voltage load unit (4), direct-current power provided by stepping down the intermediate voltage (Vm) of direct-current power output from the step-down DC/DC converter (52) at a constant step-down ratio.
