摘　　要：针对传统两线圈结构系统效率受线圈错位影响较大的问题,定量分析了三线圈结构错位对系统传输性能的影响。利用Ansoft有限元法分析S-S型磁耦合谐振式无线电能传输系统中,中继线圈不同方向错位对系统传输性能的影响;构建了24种错位模型,比较各参数的影响权重。副边线圈移动对系统传输效率的影响小于副边线圈与中继线圈共同移动对系统传输效率的影响,且横向偏移比纵向偏移影响更大。搭建实验平台进行验证,分析表明实验结果与仿真结果不一致是由单边线圈错位增加的杂散电容造成的。Aiming at the problem that coil misalignment greatly affected traditional two-coil system efficiency,a three-coil structure misalignment influence on the transmission performance was analyzed.Ansoft finite element method was used to analyze the influence of repeating coil misalignment in different directions on the transmission performance of S-S magnetic coupling resonance radio energy transmission system.Twenty-four misalignment models were constructed and the influence weights of each parameter were compared.The influence of secondary coil moving on system transmission efficiency was less than the combined moving of the secondary coil and repeating coil together,and the influence of lateral offset was greater than that of longitudinal offset.The experimental platform was built to verify the results,which shows that the inconsistency between the experimental results and the simulation results was caused by the stray capacitance increased by the misalignment of the single side coil.
