A power conversion apparatus includes a rotating electrical machine equipped with star-connected windings and an inverter equipped with series-connected units made up of upper arm switches and lower arm switches. The power conversion apparatus also includes a connecting path which electrically connects a negative terminal of a first electrical storage, a positive terminal of a second electrical storage connected in series with the first electrical storage, and a neutral point of the windings together, a connecting switch which is disposed in the connecting path, and a determiner which works to determine whether the connecting switch is required to be turned on, and a controller which turns on the connecting switch when it is determined by the determiner that the connecting switch is required to be turned on to execute a switching control operation on the upper arm switches and the lower arm switches.
