PROBLEM TO BE SOLVED: To provide a power conditioner capable of operating more reliably at an interruption of service of a system power supply, and of extracting a power from an electric automobile more reliably to supply it to an external load, such as a domestic load.SOLUTION: A power conditioner 1 comprises: a DC-DC converter 11 that converts a DC voltage inputted from an accumulator battery 21 of an electric automobile 2 into a different DC voltage; a DC-AC converter 12 that converts the converted DC voltage into an AC voltage, and gives an external domestic load 4 it; a control circuit 13 that controls the DC-DC converter 11 and the DC-AC converter 12; a power supply circuit 14 that supplies a power inputted from a system power supply 3 to the control circuit 13 as a power supply; and an external power supply input terminal 16 that is an input part. The external power supply input terminal 16 supplies to the control circuit 13 a power inputted from an external power supply, such as a different system power supply battery 22 in the electric automobile 2.SELECTED DRAWING: Figure 1 |
