Abstract
A method for wireless power transfer adapts to changing configuration of receivers, including changes in number of, location and/or orientiation of, magnetic coupling to, and load of circuits (e.g., battery charging circuits) of one or more receivers. The adaptation can be performed without interrupting optimal or near-optimal power transfer to the receivers, and can provide a measure of fairness among multiple receivers.
