Abstract
A tunable resonator assembly includes a resonator coil having an inductance, and a tile residing at a position relative to the resonator coil the position selected to produce a desired change in the inductance of the resonator coil.
Claims20
A source for transferring power wirelessly to a receiving device, the source comprising:
- a resonator coil having an inductance;
- a tile contacting the resonator coil and movable relative to the resonator coil;
- and
- a controller configured so that during wireless power transfer from the source to the receiving device, the controller:
- receives a feedback signal comprising information about the wireless power transfer between the source and the receiving device;
- and
- adjusts a position of the tile relative to the resonator coil based on the feedback signal to change the inductance of the resonator coil, thereby regulating the wireless power transfer.

A method of wireless power transfer from a source to a receiving device, the method comprising:
- receiving a feedback signal comprising information about wireless power transfer between the source and the receiving device;
- and
- regulating the wireless power transfer between the source and the receiving device by adjusting a position of at least one tile that contacts a resonator coil of the source based on the feedback signal,
- wherein adjusting the position of the at least one tile changes an operating parameter of the source.
