摘　　要：为提高磁耦合谐振式无线电能传输(MCR-WPT)系统的输出功率与输出稳定性,采用互感模型对LCL-S型MCR-WPT拓扑结构的等效电路进行了分析,获取了输出功率和传输效率的表达式,提出了系统参数配置方法;完成了应用于小功率用电设备的LCL-S型MCR-WPT系统的参数配置,设计了工作频率为124 kHz、发射线圈与接收线圈间距为12 cm的LCL-S型MCR-WPT系统;通过仿真分析与实验设计,研究了实际应用的负载动态性及发射线圈和接收线圈相对位置的不确定性对设计系统传输特性的影响。分析与实验结果表明:通过对LCL型MCR-WPT系统进行合理参数配置,可提高系统的输出功率和输出稳定性,其中输出稳定性提高了4%。In order to improve the output power and the output stability in the magnetically-coupled resonant wireless power transfer(MCR-WPT) system, we analyzed the equivalent circuit of MCR-WPT topology of LCL-S type by use of mutual inductance model. From the point of view of system design, the method of parameter configuration was studied. The formula of output power and transmission efficiency was obtained, and the parameter setting method was put forward. The parameters about the LCL-S type MCR-WPT system used for low power electrical equipment was obtained. The system in which the frequency is 124 kHz and the distance between the emitting coil and the receiving coil is 12 cm was designed. Aiming at the dynamics of the load and the uncertainty of the relative position between a emitting coil and a receiving coil in practice, we investigated the effects on the transmission characteristics of the design system by simulation analysis and test design. The analysis and the test show that the output power and the stability of the wireless power transmission system can be improved with reasonable parameter configuration of the LCL-S type MCR-WPT system. The output stability can be increased by 4%.
