摘要：
A power conversion device is applicable to three or more charge storage units (11 to 16) connected in series. The power conversion device includes: a rotating electric machine (30) including a stator winding (31); an inverter (20) including upper and lower arm switches (SWH, SWL) and connecting the stator winding and the charge storage units; a high potential path (LP) connected to a high potential terminal of the upper arm switch; a low potential path (LN) connected to a low potential terminal of the lower arm switch; a neutral point path (LM) connected to a neutral point of the stator winding; and neutral point switches (SM1 to SM5) installed individually corresponding to cell connection points (PB 1 to PB5) 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.
