Claim:
1. A wireless power receiver comprising: an inductive element configured to receive wireless power from an electromagnetic field associated with a wireless power transmitter; a circuit comprising a plurality of capacitive elements connected to the inductive element, the plurality of capacitive elements configured to supply an output current to a load; and a controller configured to selectively connect the plurality of capacitive elements to the inductive element in a plurality of configurations, the plurality of capacitive elements presenting substantially a same total reactance to the inductive element in each of the plurality of configurations, each of the plurality of capacitive elements contributing to the total reactance in each of the plurality of configurations, and each of the plurality of configurations providing a different output current to the load for a given base current in a primary inductor of the wireless power transmitter.
