Abstract

The power conversion device includes an inverter circuit in which one or a plurality of current limitation circuits that limit an electric current flowing in each of legs are provided and a control unit that controls, when a target voltage or a target current of the inverter circuit is outside a predetermined range, the current limitation circuits such that the electric current flowing in each of the legs is not limited and alternately performs the ON/OFF control of the two switching elements of each of the legs with a dead time in between and controls, when the target voltage or the target current is within the predetermined range, the current limitation circuits such that the electric current flowing in each of the legs is limited and alternately performs the ON/OFF control the two switching elements of each of the legs of the inverter circuit without the dead time in between.
