Abstract
A power conversion device may include a first inverter to which a first end of each phase winding of the electric motor is coupled; a second inverter to which a second end of each phase winding is coupled; a first phase isolation relay circuit structured to switch between connection and disconnection of the one end of each phase winding to and from the first inverter; and a first neutral point relay circuit to which the one end of each phase winding is coupled and which is structured to switch between connection and disconnection of the one end of each phase winding to and from the one end of each other phase winding.
