Abstract:
A method for operating a wireless power transmission system includes providing a driving signal for driving a transmission antenna of the wireless power transmission system, the driving signal based, at least, on an operating frequency for the wireless power transmission system. The method further includes inverting, by the at least one transistor, a direct current (DC) input power signal to generate an AC wireless signal at the operating frequency, based on provided driving signals. The method includes receiving, at a damping circuit, damping signals configured for switching the damping transistor to one of an active mode and an inactive mode to control signal damping, wherein the damping signals switch to the active mode periodically. The method further includes selectively damping, by the damping circuit, the AC wireless signals, during transmission of the wireless data signals if the damping signals set the damping circuit to the active mode.
