Abstract
A power receiving apparatus to which power is transmitted from a power transmission apparatus through electric field coupling includes a parallel resonance circuit in which an active electrode and a passive electrode are connected, a capacitor and a first switch that change a resonance condition of the parallel resonance circuit, and a second switch that supplies or cuts off an AC voltage, outputted from the parallel resonance circuit, to or from a load. The power receiving apparatus also includes a communication unit that notifies of the start of communication with the power transmission apparatus and receives a response to the notification, a first switching unit that generates a signal to be sent to the power transmission apparatus, and a second switching unit that connects or disconnects the second switch based on the response received by the communication unit.
