A power conversion device is applicable to three or more charge storage units connected in series. The power conversion device includes: a rotating electric machine including a stator winding; an inverter including upper and lower arm switches and connecting the stator winding and the charge storage units; a high potential path connected to a high potential terminal of the upper arm switch; a low potential path connected to a low potential terminal of the lower arm switch; a neutral point path connected to a neutral point of the stator winding; and neutral point switches installed individually corresponding to cell connection points each between a positive electrode terminal and a negative electrode terminal of adjacent charge storage units in the charge storage units, the neutral point switches connecting the cell connection points and the neutral point path.
