The mathematical model of magnetic resonance wireless energy transmission is analyzed,and the sys-tem structure is designed reasonably. It focuses on the detailed analysis about the loss of each section of the experi-ment platform system,which includes the loss of high frequency inverter circuit analysis,resonance coil loss analy-sis,the resonant capacitor loss analysis, and high frequency rectification loss analysis. Through the quantitative analysis of the loss of each link in the system,the key part of the system efficiency improvement is found out,which provides reference for the system optimization design.%分析磁共振无线能量传输数学模型,合理地设计了系统结构.在实验条件下求出高频逆变电路损耗、谐振线圈损耗、谐振电容器损耗、高频整流损耗.通过对系统各个环节的损耗进行定量分析,找出了影响系统效率提升的关键部分,为系统优化设计提供参考.
