Abstract
A power conversion device includes a first switching unit connected between a DC power supply and an inverter circuit, a resonant circuit connected to the input of the inverter circuit and formed by connecting a capacitor, a reactor, and a second switching unit, and a control unit, wherein, during a resonant operation period in which the first switching unit is controlled to be off and the second switching unit is controlled to be on, the control unit controls the inverter circuit to shift from a mode in which current flows back through one of upper and lower arms of the inverter circuit to a mode in which current flows back through the other arm, and provides a period in which the upper and lower arms for every phase of the inverter circuit are turned on simultaneously.
