Abstract
Examples of charging systems are described which may utilize a network of resonator circuits. Control methods are described which may locate a charging location at which an electronic device is placed proximate the charging system and identify a path of resonator circuits to activate to charge the electronic device. Individual resonator circuits in the path may be activated by selecting a resonant frequency of the resonator circuit such that power may be transferred by the resonator circuit at an operating frequency.
Claims24
An apparatus comprising:
- a plurality of resonator circuits, each comprising:
- a resonator;
- and
- a control circuit coupled to the resonator;
- a controller coupled to the plurality of resonator circuits, the controller configured to provide control signals to the control circuit of each of the plurality of resonator circuits, the control signals configured to control selected ones of the plurality of resonator circuits to have a first resonant frequency and other ones of the plurality of resonator circuits to have a second resonant frequency, wherein the first resonant frequency is configured to transmit power at an operating frequency.
