Abstract
To provide a power conversion device that is effective for improving controllability of power in power conversion for multilevel voltage output. A power conversion device includes a switching circuit configured to supply a current to a motor by connecting and disconnecting a first point having a first potential, a second point having a second potential greater than the first potential, and a neutral point having a neutral potential between the first potential and the second potential to and from the motor, a neutral potential control unit configured to control the switching circuit in a manner to maintain the neutral potential within a target range, and a current control unit configured to increase a supply current to the motor without affecting a driving force generated by the motor at least when controlling the switching circuitby the neutral potential control unit.
