<P>PROBLEM TO BE SOLVED: To provide a power conversion device that implements a self-sustaining operation without requiring a dedicated power conversion circuit. <P>SOLUTION: A power converter 1 comprises: a DC/DC unit 2 for converting a DC voltage supplied from an electric vehicle V to a first DC voltage for a house 20 or a second DC voltage for an electric apparatus 23; a first power line L1 for outputting the converted first DC voltage; a second power line L2 for outputting the converted second DC voltage; a relay 3; an external connection section 4 connectable with the electric apparatus 23; and a control section 5 for controlling the DC/DC unit 2 and the relay 3. The control section 5, in a steady state, controls the DC/DC unit 2 so as to convert the DC voltage to the first DC voltage and controls the relay 3 to an interruptive state to supply the first DC voltage via the first power line L1, and when the first power line L1 is disconnected, controls the DC/DC unit 2 so as to convert the DC voltage to the second DC voltage and controls the relay 3 to a supply state to supply the second DC voltage via the second power line L2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
