Abstract
A method for adaptively optimizing wireless charging efficiency is disclosed. The method may comprise providing an input power to a power transmitter, the power transmitter comprising a transmitter-side coil wirelessly coupled to a receiver-side coil of a power receiver, determining, at the power receiver, a real power transferred from the power transmitter, transmitting information associated with the determined real power to the power transmitter through the coupling between the receiver-side coil and the transmitter-side coil, and adjusting, at the power transmitter, the input power in response to determining, according to the transmitted information, that the real power differs from an expected power corresponding to the input power by over a first threshold, causing the real power to tune towards the expected power.
