摘要： A power conversion apparatus (102) includes arms (104) in each of which one or more unit converters (105) each including a capacitor (203) and capable of outputting an arbitrary voltage are connected in series, and a point P as a first node to which one ends of the respective arms (104) are Y-connected, and a point N as a second node to which a neutral terminal of the rotary electric machine (103) is connected. The other ends of the respective arms are connected to one ends of respective phase windings of a rotary electric machine.
