| 主权项 | 1. An apparatus comprising a receiving device adapted to receive energy wirelessly by resonant inductive coupling from a feeding device comprising a supply source, the receiving device comprising: monitoring circuitry configured to monitor a resonant frequency of a supply source, the monitoring circuitry comprising a measurement coil; a receiving component comprising at least one inductor; and a phase locked loop circuit configured to output a control signal based upon signals induced at the inductor and the measurement coil; and a control unit configured to vary a resonant frequency of said receiving component in dependence upon the control signal,wherein the apparatus is configured to match the resonant frequency of said receiving component with the resonant frequency of said supply source. | ||
