Abstract:
A power receiver is configured to supply current to a load and to be wirelessly operatively coupled to a power transmitter and includes a plurality of inductive elements. The power receiver further includes a circuit operatively coupled to the plurality of inductive elements and configured to be selectively switched among a plurality of coupling states. The circuit is further configured to be selectively switched such that each inductive element has a reactance state of a plurality of reactance states. The power receiver further includes a controller configured to select the coupling state and to select the reactance state of each inductive element based on one or more signals indicative of one or more operating parameters of at least one of the power receiver and the power transmitter.
