Abstract
An energy transferring system including a source-side resonator, an intermediate resonant module, and a device-side resonator is provided. The three resonators substantially have the same resonant frequency for generating resonance. The energy on the source-side resonator is coupled to the intermediate resonant module, such that non-radiative energy transfer is performed between the source-side resonator and the intermediate resonant module. The energy coupled to the intermediate resonant module is further coupled to the device-side resonator, such that non-radiative energy transfer is performed between the intermediate resonant module and the device-side resonator to achieve energy transfer between the source-side resonator and the device-side resonator. The coupling coefficient between the intermediate resonant module and its two adjacent resonators is larger than the coupling coefficient between the source-side resonator and the device-side resonator. The invention has the advantages of high transmission efficiency, small volume, low cost.
