资料介绍

以磁耦合谐振理论为基础,建立了三线圈无线电能传输系统的模型,运用等效电路理论和二端口网络理论推导出三线圈无线电能传输系统的传输效率公式。利用该公式对发射一接收线圈之间的交叉耦合系数进行了理论分析。理论分析结果表明,交叉耦合系数较大时系统的传输效率会降低。仿真结果验证了理论分析的正确性。

Based on the theory of magnetic resonance coupling, a model of three coil system for wireless power transmission was established, and the transmission efficiency formula was derived by applying equivalent circuit theory and two port network theory. Cross coupling coefficient between transmitting and receiving coils was analyzed theoretically by using the formula. The theoretical analysis results show that the transmission efficiency of the system should decrease if cross coupling coefficient is large enough. The simulation results verify the correctness of the theoretical analysis.
