Abstract: In a power converter, a first DC-DC converter converts a DC voltage output from a DC power supply into a DC voltage of a different level. A DC-AC converter converts a DC power output from the first DC-DC converter into an AC power and supplies the AC power to an AC load. A variable load unit connected to a current path that branches from a node between the first DC-DC converter and the DC-AC converter. A controller adjusts the variable load unit so that a total of a power consumption in the AC load and a power consumption in the variable load unit is equal to or larger than a predetermined power value.
