Abstract
A power conversion device includes a reactor, a single-phase inverter, and a single-phase converter which are connected in series to each other between an AC power supply and a smoothing capacitor, and performs power conversion between AC voltage of the AC power supply and DC voltage of the smoothing capacitor. The power conversion device includes a control unit which controls switch elements of the single-phase inverter and switch elements of the single-phase converter so that charging operation and discharging operation of the DC capacitor are performed in one switching cycle of the single-phase inverter and the charging amount and the discharging amount thereof are equal to each other.
