Abstract
A power conversion device includes: a rectifying unit rectifying an AC voltage output from an AC power supply; a booster circuit boosting an output voltage of the rectifying unit; a control unit causing the booster circuit to perform synchronous rectification; and a smoothing capacitor smoothing an output voltage of the booster circuit. The booster circuit is constituted by connecting a plurality of chopper circuits in parallel to each other, the chopper circuits each including an upper arm switching element and a lower arm switching element connected in series to a reactor connected to the rectifying unit, and the control unit generates a drive pulse causing the upper arm switching element to be turned on when a reverse current flows through the upper arm switching element.
