Claim:
1. A power receiving device comprising: an antenna configured to receive a first AC power and a modulation signal; a rectifier circuit configured to rectify the first AC power into DC power; a power storage device configured to store the DC power; a communication control unit to which a second AC power including the modulation signal is input; and a transformer between the antenna and the rectifier circuit, wherein a first terminal of the rectifier circuit and a third terminal of the transformer are electrically connected to a first node, wherein a second terminal of the rectifier circuit and a fourth terminal of the transformer are electrically connected to a second node, wherein a third terminal of the rectifier circuit and one electrode of the power storage device are electrically connected to a third node, wherein a maximum potential of the first AC power is a potential of the first node, wherein a minimum potential of the first AC power is a potential of the second node, wherein a potential of the DC power stored in the power storage device is a potential of the third node, wherein a voltage amplitude of the first AC power is the same as a voltage amplitude of the second AC power, and wherein an intermediate potential of the first AC power is different from an intermediate potential of the second AC power.
