Abstract
A wireless power reception apparatus includes a reception (RX) resonator configured to form a resonance coupling with a first resonance period associated with an envelope of a power to receive the power from a transmission (TX) resonator; a switch controller configured to generate, at intervals of the first resonance period, a control signal to deactivate the RX resonator at an off timing corresponding to a time instant at which a maximum energy is stored in an inductor of the RX resonator; and a switch configured to deactivate the RX resonator in response to the control signal.
