Abstract

See full text

A device operative to transfer power and communicate wirelessly includes a drive-sense circuit (DSC), memory that stores operational instructions, and processing module(s). The DSC generates a drive signal based on a reference signal and provides the drive signal to a first coil via a single line and via a resonating capacitor, and simultaneously senses the drive signal via the single line, to facilitate electromagnetic coupling to a second coil to transfer power wirelessly to another device. The DSC also detects electrical characteristic(s) of the drive signal including whether a communication signal is transmitted from another device and generates a digital signal representative thereof. The processing module(s) generates the reference signal, processes the digital signal including to determine whether the communication signal is transmitted from the other device to the device and appropriately processes the digital signal to interpret control information of the communication signal to adapt the reference signal.
