Abstract
This power reception apparatus is provided with a non-contact power reception antenna, a power supply unit, a communication antenna, a communication unit that performs communication via the communication antenna, a communication switch, and a switch control unit. The power supply unit outputs an output voltage corresponding to power received via the power reception antenna. The communication switch can transit between an electrically connected state wherein the communication unit is electrically connected to the communication antenna, and a disconnected state wherein the communication unit is disconnected from the communication antenna. The switch control unit makes the communication switch transit to the disconnected state when the output voltage of the power supply unit is increased over a first voltage, and the switch control unit makes the communication switch transit to the electrically connected state when the output voltage is reduced to below a second voltage that is lower than the first voltage.
