    摘要: The disclosure provides systems, methods, and apparatus for wireless power transfer. In one aspect, an apparatus configured to receive wireless power from a transmitter is provided. The apparatus includes an inductor having an inductance value. The apparatus further includes a capacitor electrically connected to the inductor and having a capacitance value. The apparatus further includes an optimizing circuit configured to optimize transfer efficiency of power received wirelessly from the transmitter, provided that an amount of the power received wirelessly and provided to a load is greater than or equal to a received power threshold, or optimize the amount of the power received wirelessly from the transmitter, provided that the power transfer efficiency is greater than or equal to an efficiency threshold.

    摘要: A wireless power transmission system is disclosed. In one aspect, the system includes a transmitting antenna configured to transmit power, via a magnetic field, to a receiving antenna to power a load. The system also includes a tuning loop electrically isolated from the transmitting antenna and being movable relative to the transmitting antenna to adjust a coupling between the transmitting antenna and the tuning loop.
