<p>This power receiving apparatus is provided with a power receiving antenna, a rectifying circuit, a communication unit, a switch unit, and a switch control unit. The power receiving antenna is used for the purpose of both the communication and power reception. The rectifying circuit converts power into a direct current voltage, said power having been received by means of the power receiving antenna, and outputs the direct current voltage. The communication unit performs communication via the power receiving antenna. The switch unit is connected to between the power receiving antenna and the communication unit. The switch unit is capable of transitioning between a conductive state wherein the communication unit is electrically connected to the power receiving antenna, and a disconnected state wherein the communication unit is electrically disconnected from the power receiving antenna. The switch control unit is connected to the rectifying circuit. The switch control unit makes the switch unit transition to be in the disconnected state when the power receiving antenna has started to receive the power, and the direct current voltage outputted from the rectifying circuit exceeds a first threshold value. The switch control unit makes the switch unit transition to be in the conductive state when the direct current voltage becomes lower than a second threshold value that is different from the first threshold value.</p> |
