摘要：
Wireless energy transfer apparatus include, in at least one aspect, a device resonator configured to supply power for a load by receiving wirelessly transferred power from a source resonator； a temperature sensor positioned to measure a temperature of a component of the apparatus； a tunable component coupled to the device resonator to adjust a resonant frequency of the device resonator, an effective impedance the device resonator, or both； and control circuitry configured to, in response to detecting a temperature condition using the temperature sensor, (i) tune the tunable component to adjust the resonant frequency of the device resonator, the effective impedance of the device resonator, or both, and (ii) signal the source resonator regarding the temperature condition to cause an adjustment of a resonant frequency of the source resonator, a power output of the source resonator, or both.
