WIRELESS POWER RECEIVER SYSTEM

摘要

A wireless power receiver capable of receiving wireless power from close-coupled and mid-range wireless power supplies. The wireless power receiver includes a principal and supplemental receiver circuits. The principle receiver circuit is adjustable to operate in a close-coupled mode or a resonator mode. In close-coupled mode, the principle receiver circuit is coupled to the power input of a remote device and functions as the principle power source. In resonator-mode, the principle power circuit is electrically disconnected/isolated from the remote device and forms a closed resonant loop to function as a resonator that amplifies an electromagnetic field from a mid-range wireless power supply. The supplemental receiver circuit is coupled to the power input of the remote device and is configured to receive wireless power from the resonator and function as the power source when the principle receiver circuit is in the resonator mode.
