A power converter 1 includes: a DC/DC unit 2 converting DC voltage supplied from an electric vehicle V to a first DC voltage for a home 20 or a second DC voltage for an electric appliance 24; a first power line L1 outputting the first DC voltage; a second power line L2 outputting the second DC voltage; a relay 3; an external connector 4 to which the electric appliance 24 is connected; and a controller 5 controlling the DC/DC unit and relay 3. During regular operation, the controller 5 causes the DC/DC unit 2 to convert the DC voltage to the first DC voltage and brings the relay 3 into a disconnected state to supply the first DC voltage via the first power line L1. When the first power line L1 is offline, the controller 5 causes the DC/DC unit 2 to convert the DC voltage to the second DC voltage and brings the relay 3 into a feeding state to supply the second DC voltage via the second power line L2.
