Abstract
This paper analyses and designs a kind of wireless power transmission system via coupled magnetic resonances. It introduces the wireless power transmission technology, and expounds the principle of coupled magnetic resonant wireless power transmission technology and its superiority. Then it analyzes the influence of the related parameters such as the transmission distance d and load resistance R L of the emitting and receiving resonant coils on the transfer efficiency and transfer power of the system. The experiment tests the proposed wireless power transmission system, and the results show that the above relevant parameters should be comprehensively considered, in order to achieve the optimization design of the transmission efficiency or transmission power. The experiment results also show the validity of the theoretical analysis.
