Abstract

The present disclosure includes an inverter connected to a power supply unit via a positive electrode side electrical path and a negative electrode side electrical path and including switching elements, a rotary electric machine including windings connected to each other at a neutral point and inputting and outputting power from and to the power supply unit via the inverter, a connection path electrically connecting an intermediate point between the storage batteries of the power supply unit to the neutral point of the windings, and a device including a first terminal and a second terminal enabling energization between the power supply unit and the device. The first terminal is connected to the connection path, and the second terminal is connected to at least one of the positive electrode side electrical path and the negative electrode side electrical path.
