Abstract: A power conversion apparatus includes: a rotating electric machine that has a winding; an inverter that has a series-connection body of an upper arm switch and a lower arm switch; and a capacitor that is connected in parallel to the series-connection body. The power conversion apparatus includes: a connection path that, in a first storage battery and a second storage battery that are connected in series, electrically connects the winding with both a negative-electrode side of the first storage battery and a positive-electrode side of the second storage battery; and a control unit that controls switching of the upper arm switch and the lower arm switch such that a current flows between the first storage battery and the second storage battery through the inverter, the winding, and the connection path.
