Abstract:
An inverter circuit including a DC capacitor is connected in series to an AC power supply, and at the stage subsequent to the inverter circuit, a smoothing capacitor is connected via a converter circuit. A short-circuit period T for short-circuiting the AC terminals of the converter circuit is provided in one cycle, whereby the converter circuit is controlled, and PWM control is performed for the inverter circuit so as to improve an AC power supply power factor. When current control by the inverter circuit cannot be performed, the PWM control is switched to PWM control for the converter circuit, to perform current control.
