A power conversion device may include a first inverter to which a first end of each phase winding is coupled; a second inverter to which a second end of each phase winding is coupled; a plurality of switching elements provided in the first and second inverters; a control circuit structured to perform n-phase conduction control on the first and second inverters; and a detection circuit structured to detect a failure in the switching elements. The control circuit is structured such that, when the detection circuit has detected a failure in any of the plurality of switching elements, the control circuit changes the control of the first and second inverters from the n-phase conduction control to m-phase conduction control using m phases of the n phases different from the phase of a winding coupled to the failed switching element, m being an integer not smaller than two and smaller than n.
