Abstract
In accordance with aspects of the present invention, a first wireless power enabled device includes a transceiver and control logic. The transceiver includes a plurality of switches coupled in a full-bridge configuration with a resonant tank circuit. The control logic is configured to detect a presence of a second wireless power enabled device, establish a trusted relationship with the second wireless power enabled device, determine an operating mode of the first wireless power enabled device selected from a transmit mode or a receive mode, and drive the plurality of switches to operate the resonant tank circuit in the determined operating mode. The first wireless power enabled device may further include a memory that stores a copy of a first key associated with the first wireless power enabled device and a copy of a second key associated with the second wireless power enabled device.
