Abstract
A power receiving device used for wirelessly supplying power from a power supply device using electromagnetic resonance to an electronic apparatus which receives power by electromagnetic induction is provided. The power receiving device includes a first antenna coupled with an antenna of the power supply device by electromagnetic resonance, a second antenna coupled with the first antenna by electromagnetic induction, a load, a switching circuit, a control circuit, and an input device. A signal for selecting switching of the switching circuit is generated in the control circuit in response to a command from the input device. A connection between the second antenna and the load is controlled by switching of the switching circuit in response to the signal.
