Abstract: A voltage dedicated charger apparatus includes an AC-to-DC converter circuit, a pair of switches, and a controller block. The AC-to-DC converter circuit converts an AC input voltage to a DC output voltage. The pair of switches is operable to isolate a pair of data ports from the AC-to-DC converter circuit. The pair of data ports includes a DP port and a DN port. The controller block includes a monitor circuit, a transceiver, and a control circuit. The monitor circuit monitors the DP and DN ports of the apparatus. The transceiver receives one or more messages form a charge-receiving device and communicate data to the charge-receiving device. The control circuit controls operation of the pair of switches based on a signal from the monitor circuit.

Abstract: A wireless power transfer system is described that includes a power station and a chargeable device. The power station transmits discovery beacons in order to detect a chargeable device within its vicinity using any available communication protocols and/or standards. Once a device is discovered, the power station can perform coil selection with the device in order to select preferred coils for power transfer. In addition, the chargeable device is capable of detecting the beacon signal and providing a response to notify the power station of its presence. The chargeable device is capable of performing its own coil selection for further optimization and includes various assistance functionality to aid a user in optimizing a connection with the power station.
