Abstract:
1. A wireless power transfer system with at least one adjustable magnetic resonator comprising: a first magnetic resonator with a plurality of differently sized inductive elements; at least one power and control circuit configured to selectively connect to at least one of the plurality of differently sized inductive elements; one or more additional magnetic resonators separated from the first magnetic resonator; and measurement circuitry to measure at least one parameter of a wireless power transfer between the first magnetic resonator and the one or more additional magnetic resonators, wherein one or more connections between the plurality of differently sized inductive elements and the at least one power and control circuit are configured to change an effective size of the first magnetic resonator according to the at least one parameter measured by the measurement circuitry.
