摘　　要：无线电能传输(WPT)系统具有高阶、非线性及强耦合的特点,建立与实际系统相近的模型结构对设计高性能WPT系统具有重要意义。此处以LCL-S补偿结构的WPT系统为研究对象,根据次级电路工作特点建立整流器负载等效阻抗模型,基于等效阻抗模型对谐振补偿参数设计进行优化。仿真与实验结果表明,所建立的等效阻抗模型精准度较高,采用优化后的谐振补偿参数系统输出功率提升显著。The wireless power transfer(WPT)system has the characteristics of high-order,nonlinearity and strong coupling.Establishing a model structure similar to the real system is important for designing high performance WPT systems.The WPT system is taken with LCL-S compensation structure as the research object,the equivalent impedance model of rectifier load is established according to the working characteristics of secondary circuit,and the design of resonance compensation parameters is optimized based on the equivalent impedance model.The simulation and experimental results show that the accuracy of the equivalent impedance model is high,and the output power of the system with the optimized resonance compensation parameters is significantly improved.
