Abstract
Wireless power transfer systems, disclosed, include a wireless power transmission system and a wireless power receiver system. The wireless power transmission system includes a transmitter antenna configured to couple with a receiver antenna to transmit alternating current (AC) wireless signals to the receiver antenna. Antenna coupling may be inductive and may operate in conformance to a wireless power and data transfer protocol. A transmission controller drives the transmitter antenna at an operating frequency, and either the wireless power transmission system or the wireless power receiver system may damp the wireless power transmission to create a data signal containing a serial asynchronous data signal.
