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 switching between modes, the amount of energy received by the adaptive receiver may be controlled. This control is a form of adaptive resonance control or Q control.
