PROBLEM TO BE SOLVED: To provide a power conversion device capable of supplying desired AC output power to loads without imposing excessive burden on an on-vehicle battery.SOLUTION: A power conversion device 1 includes: a power conversion unit 2 for supplying AC output power to loads R through a service wire 12; and a control unit 3 for controlling the power conversion unit 2 so as to allow a voltage value to be detected by a voltage detection unit 8 to be a target voltage value. The control unit 3 includes: a correction value determination unit 4 for determining the correction value of the target voltage value on the basis of the current value of a current flowing in the service wire 12; and a target voltage resetting unit 6 for determining whether an on-vehicle battery 10 can supply DC power to be required when the voltage value of the AC output power is defined as the sum of the target voltage value and the correction value or not based on information related to the on-vehicle battery 10, setting the sum of them as a new target voltage value when the supply is possible, and setting a value obtained by maximally performing addition to the target voltage value within a suppliable range as a new target voltage value when the supply is impossible. |
