CONTACTLESS POWER RECEIVER AND METHOD FOR OPERATING SAME

摘要

A contactless power system comprising a power transmitter having a transmitting coil and a power receiver having a receiving coil, the power receiver being configured to receive power transmitted by the power transmitter via contactless electromagnetic coupling of the respective coils and deliver the received power to a load, wherein the receiving coil of the power receiver is part of a resonant circuit having a resonant frequency, the resonant circuit comprising a detuning element to detune the frequency of the resonant circuit from the resonant frequency in accordance with power requirements of the load.
