Abstract
A wireless power transmission system includes a transmitter antenna, an amplifier, and a transmitter controller. The transmitter antenna is configured to transmit wireless power signals and wireless data signals. The amplifier is configured to receive a driving signal at a gate of the at least one transistor and invert a direct power (DC) input power signal to generate the AC wireless signal at the operating frequency. The transmitter controller is configured to configure the driving signal based, at least, on an operating frequency and an initial beaconing process, the initial beaconing process for determining presence of a wireless receiver system at a coupling between the transmitter antenna and a receiver antenna of the wireless receiver system, determine amplifier voltage instructions for the amplifier based on the initial beaconing process, and drive the amplifier by providing the driving signal and the amplifier voltage instructions to the amplifier.
