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.
