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.

Abstract: A power supply apparatus includes a storage battery and supplies a voltage from the battery to an electric load. The power supply apparatus includes first and second energizing paths connected in parallel between the battery and the load, a first switch making the first energizing path conductive and interrupting the first energizing path, and a second switch making the second energizing path conductive and interrupting the second energizing path. The power supply apparatus includes a first drive circuit that operates when a voltage is supplied and drives the first switch, a second drive circuit that operates when a voltage is supplied and drives the second switch into a conductive state in a case where the first switch is driven into a conductive state by the first drive circuit, first and second supply paths respectively supplying a voltage to the first and second drive circuits.
