摘要
以互感理论分析了磁耦合谐振式无线电能传输系统原理,介绍了阻抗匹配理论及相应的参数计算方法,提出将收、发线圈互感的变化等效成系统阻抗参数的改变,建立了含有阻抗匹配器的磁耦合谐振式无线电能传输系统模型。仿真结果验证了在相同的条件下,具有阻抗匹配器的磁耦合谐振式无线电能传输系统可有效提高负载功率。
Principle of magnetic resonance coupling wireless power transmission system was analyzed by use of mutual inductance theory.Impedance matching theory and corresponding parameter calculation methods were introduced.A model of magnetic resonance coupling wireless power transmission system containing an impedance matcher was built by equaling variation of mutual inductance between sending coil and receiving coil to variation of the system impedance parameters.The simulation result proves that magnetic resonance coupling wireless power transmission system containing an impedance matcher can improve load power effectively under the same condition.
