Duties of control for DC/AC and DC/DC conversion units are determined by considering electric influences of a filter circuit, a capacitor connected to a DC bus, and a DC reactor for an output voltage command value for supplying an AC voltage to a load. The DC/DC conversion unit is controlled to convert a DC voltage into a DC bus voltage waveform alternately having a period of a pulsating current waveform corresponding to the absolute value of the AC voltage and a period of the DC voltage as a pulsating current minimum value. The DC/AC conversion unit is controlled to perform step-down operation during the period of the DC voltage and thus perform conversion into a waveform of the absolute value of the AC voltage corresponding to the period of the DC voltage, and also to perform polarity inversion per one pulsating current cycle.

Control is performed such that, for generating an AC voltage from a DC voltage, a period during which a DC/DC converter boosts the DC voltage and an inverter performs one of polarity non-inversion passing and polarity inversion passing, and a period during which the DC/DC converter is stopped and the inverter performs step-down operation and one of polarity non-inversion passing and polarity inversion passing, arise alternately in one AC cycle. Gate blocking is temporarily performed for only the DC/DC converter, upon occurrence of a phenomenon in which, by start of power feeding to a load connected to an AC electric path, an absolute value of a current flowing through an AC reactor reaches a predetermined converter gate block threshold value lower than an instantaneous overcurrent protection threshold value.
