Abstract
A power conversion device includes a rectifier circuit that converts an AC power from an AC power supply, into a DC power, a short-circuit unit that short-circuits the AC power supply via a reactor connected between the AC power supply and the rectifier circuit, a control unit that generates a plurality of drive signals to control the short-circuit unit in a half cycle of the AC power supply, and a smoothing capacitor. The control unit stepwise varies threshold values that limit a value of a power-supply current of the AC power supply, in an on-section or an off-section of the plurality of drive signals.
