Abstract:
A remote device in accordance with the present invention includes an adaptive power receiver that receives wireless power from the wireless power supply by induction. The adaptive power receiver may be switched among two or more modes of operation, including, for example, a high-Q mode and a low-Q mode. By controlling the duty cycle of the switching between modes, the amount of energy received by the adaptive receiver may be controlled to communicate to the wireless power supply. This control is a form of adaptive resonance communication or Q control communication. Distortion can be reduced or eliminated by ramping between duty cycles with adjustment to intermediate duty cycle values.
