<p>The invention provides a power converter including a plurality of power conversion units each connected to a different feeder, a DC energy interchange unit connected to the power conversion units and connected to a secondary battery, and a power control unit which instructs the regeneration-side power conversion unit connected to the regeneration-side feeder of the feeders, through which a regenerative current flows, and the consumption-side power conversion unit connected to the consumption-side feeder through which a current consumption flows, to output power from the regeneration-side feeder to the consumption-side feeder through the DC energy interchange unit. The power control unit also determines the voltage of the DC energy interchange unit in such a manner as to input/output energy corresponding to the sum of regenerative power of the regeneration-side feeder and consumed power of the consumption-side feeder to and from the secondary battery.</p> |
