Abstract
Embodiments described herein may relate to a system comprising a power source configured to provide a signal at an oscillation frequency; a transmitter coupled to the power source, wherein the transmitter comprises at least one transmit resonator; one or more receivers, wherein the at least one receive resonator is operable to be coupled to the transmit resonator via a wireless resonant coupling link; one or more loads, wherein each of the one or more loads is switchably coupled to one or more respective receive resonators. The system includes a controller configured to determine an operational state of the system, wherein the operational state comprises at least one of three coupling modes (common mode, differential mode, and inductive mode), and is configured to cause the transmitter to provide electrical power to each of the one or more loads via the wireless resonant coupling link according to the determined operational state.
