摘要: 针对三线圈无线电能传输系统中继线圈位置变化会改变系统传输性能的实际问题，研究了三线圈无线电能传输系统耦合机理；通过建立三线圈无线电能传输系统等效电路模型，推导出系统输出功率增益和传输效率基本特性公式，分析了系统输出功率增益、传输效率与特性参数的相互作用机理，得出了系统输出功率增益、传输效率各自的规律；设计开发了无线电能传输实验系统，验证了理论分析的正确性。Abstract: In view of problems that transmission performance of three-coil wireless power transmission system would change with moving of relay coil, coupling mechanism of three-coil wireless power transmission system was researched. An equivalent circuit model of the wireless power transmission system was built which is based on three-coil structure, and basic characteristic formula of output power gain and transmission efficiency were deduced. Interaction mechanism of the output power gain, transmission efficiency and characteristic parameters were analyzed, and laws of the output power gain and transmission efficiency of the system were obtained. The wireless power transmission experiment system was developed which verifies correctness of the theoretical analysis.
