<p><P>PROBLEM TO BE SOLVED: To efficiently use regenerative electric power without increasing facility cost by reducing capacity of an expensive power storage device. <P>SOLUTION: The direct current power converter, which is a component of a power converter, converts direct current power in response to a direct current power feeder voltage to transfer the direct current power between the direct current power converter and the direct current power feeder. A power storage device is connected to the direct current power converter and stores power input from the power feeder via the direct current power converter, and the stored power is output to the power feeder. An AC-DC power converter connected between an alternate power supply of a power distribution system and the power storage device converts alternate current power to the direct current power. This configuration allows to efficiently store regenerative electric power and use the stored regenerative electric power as running electric power without increasing facility cost. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
