摘　　要：根据非对称磁耦合谐振式无线电能传输系统的等效模型,指出了磁耦合谐振式无线电能传输为磁耦合感应式无线电能传输的特殊情况,即磁耦合谐振式无线电能传输只有在谐振频率处才能实现远距离能量传输;给出了抑制频率分裂的方法,即通过调整发射线圈和接收线圈轴线方向的偏转角度和径向距离来削弱互感系数,提高接收线圈的峰值电压;搭建了非对称磁耦合谐振式无线电能传输系统实验平台,实验结果验证了理论分析的正确性。According to equivalent model of asymmetrical magnetic coupled resonant wireless power transmission system, a view was pointed out that magnetic coupled resonant wireless power transmission which could maintain long distance transmission at resonance frequency was a special case of magnetic coupled inductive wireless power transmission. Methods of restraining frequency splitting were given, namely changing offset angle and radial distance of axial direction of transmitting coil and receiving coil to reduce mutual inductance coefficient and improve peak voltage of the receiving coil. Finally, experimental platform of asymmetrical magnetic coupled resonant wireless power transmission system was built and the experimental results verified correctness of theoretical analysis.
