Wireless power transmission systems and methods with selective signal damping at periodic active mode windows

A wireless power transmission system comprising:

• a transmission antenna configured to couple with at least one other antenna and transmit alternating current (AC) wireless signals to the at least one other antenna, the AC wireless signals including wireless power signals and wireless data signals, wherein the wireless data signals are one of on-off-keyed (OOK) in-band data signals or amplitude-shift-keyed (ASK) in-band data signals;
• an amplifier, the amplifier including:
• at least one transistor that is configured to (i) receive a driving signal at a gate of the at least one transistor, the driving signal configured to drive the transmission antenna based on an operating frequency for the wireless power transmission system and (ii) invert a direct current (DC) input power signal based on the driving signal, to generate the AC wireless signals at the operating frequency, and
• a damping circuit that is configured to dampen the AC wireless signals during transmission of the wireless data signals, wherein the damping circuit includes at least a damping transistor that is configured to receive damping signals configured for switching the damping transistor to one of an active mode or an inactive mode to control signal damping during transmission or receipt of wireless data signals;
• and
• a transmission controller that is configured to (i) provide the driving signals to the at least one transistor, (ii) generate the damping signals by switching the damping transistor to one of the active mode or the inactive mode to control signal damping, wherein the damping signals switch to the active mode periodically, and (iii) perform one or more of encoding the wireless data signals, decoding the wireless data signals, receiving the wireless data signals, or transmitting the wireless data signals.

A non-tangible, machine-readable medium storing instructions, which, when executed, cause a controller to:

• determine a driving signal for driving a transmitter antenna of a wireless power transmission system, the driving signal based, at least, on an operating frequency for the wireless power transmission system, the driving signals configured for generating alternating current (AC) wireless signals;
• provide the driving signal to at least one transistor of an amplifier of the wireless power transmission system at a gate of the at least one transistor;
• determine damping signals for a damping transistor of a damping circuit, the damping signals configured for switching the damping transistor to one of an active mode or an inactive mode to control signal damping, wherein the damping signals switch to the active mode periodically;
• and
• provide the damping signals to the damping circuit, the damping signals instructing the damping circuit to selectively damp the AC wireless signals based, at least in part, on wireless data signals that are in-band of the AC wireless signals.
