Abstract
A power conversion device includes a single-phase full-wave rectifying unit, an electrolytic capacitor, a plurality of chopper circuits that are arranged between the single-phase full-wave rectifying unit and the electrolytic capacitor, each of the chopper circuits including a reactor, a first MOSFET connected in parallel with the single-phase full-wave rectifying unit, and a second MOSFET connected to a positive terminal of the electrolytic capacitor at one end and to the reactor and the first MOSFET at the other end, a first current detecting unit to bidirectionally detect a current flowing through the reactor, and a control unit to control an operation of the first MOSFET by using the detection result from the first current detecting unit.
