Abstract
The invention makes it possible to secure a maximum output within the capacity range of an electrical power source by preventing an output from being cut by a protective function of a converter at the time of a temporary overload. A bidirectional DC-DC converterfor stepping up a voltage of DC power supplied from a batteryis provided. A stepped-up DC power is converted to an AC power by an inverter-via a regulator-and is outputted to the load side. An input voltage Vof the regulator-is detected by a voltage detecting portionand is inputted into an output limit determining portion. The output limit determining portiondetermines an output voltage value for starting to limit an inverter output according to a distance from when the input voltage Vfell below a limit starting voltage value Vlim to a limit voltage value Va. An inverter driving portionlimits an output by switching FETs in the inverterin accordance with this output voltage value. When a temporary overload is eliminated, then the output recovers to a maximum value.
