Abstract
A wireless power transmitter includes circuitry configured to determine a reflected impedance from a receiver coil at a transmitter coil and control a dead-time of one or more switching stages of a power conversion device based on the reflected impedance. A tunable matching network at the transmitter is controlled based on the reflected impedance and the dead-time of the one or more switching stages.
