POWER CONVERTER

A power converter includes a plurality of power conversion units connected to one another in parallel, each including an AC/DC converter (rectifier) that converts AC power from an AC input power supply (commercial power supply) into DC power, a DC/DC converter (DC power converter) that converts the DC power from the AC/DC converter, and a current detector that detects charge current flowing from the DC/DC converter as well as discharge current flowing to the DC/DC converter. The power converter further includes a battery (electrical storage unit) that is charged by a subset of DC/DC converters among the DC/DC converters of the plurality of power conversion units, as well as a CPU (controller) that controls the DC/DC converters of the plurality of power conversion units.
