A power conversion device includes a first converter connected to first ends of windings of each phase of a motor, a second converter connected to second ends of the windings of each phase, and a switching circuit used to define a neutral point in the windings of each phase on the first inverter side. At least one of a plurality of switches included in the first inverter has a first current capacity, and a plurality of switches included in the second inverter have a second current capacity that is greater than the first current capacity.
