摘要
对SS型拓扑结构的磁场耦合谐振式无线供电系统进行了建模与分析,利用交流阻抗分析法建模,着重分析自感、互感参数对系统传输功率和传输效率的影响;对应用在箭上的无线电能传输系统,考虑其电磁兼容性,分别使用铁磁性金属与非铁磁性金属对谐振器进行屏蔽,分析其对传输性能的影响;针对特定条件下的参数,提出了基于互感耦合参数的性能优化指标,为达到此指标设计相应的电磁屏蔽方案;并分析屏蔽优化后的其他指标,进行实物实验验证。
The magnetic field coupling resonant wireless power supply system with SS topology is modelled and analyzed,and the ac impedance analysis method is used to model the system.Regarding the electromagnetic compatibility of the radio energy transmission system applied to the launch vehicle,the ferromagnetic metal and non-ferromagnetic metal are used to shield the resonator respectively,and the influence of them on the transmission performance is analyzed.According to the parameters under specific conditions,the performance optimization index based on mutual inductance coupling parameters is proposed and the corresponding electromagnetic shielding scheme is designed in order to reach the index goals.Other indexes after mutual inductance optimization are analyzed and verified by experiments.
