摘要建立磁耦合机构与系统电气参数的函数模型,以能效特性作为主要目标,以磁耦合机构的结构特性及频率特性作为约束条件,提出一种具有普遍适用性的磁耦合机构设计流程。并以该文所提出的一种新型磁耦合机构为例,通过线圈组合的方式,配置相应的磁心结构,在保证能量传输距离的前提下,有效增加了系统的可充电区域。借助有限元电磁仿真平台得到相应数据及实验测量数据,证明了流程的合理性。

Abstract：In this paper,the function models of magnetic coupler and the electrical parameters are built firstly.Then the output power and efficiency are taken as the main goal,which might be affected by the structure parameters and the working frequency.After that,the design method for magnetic coupler is proposed with pervasive applicability.A new kind of magnetic coupler is then taken as the case of the method.Through coils combination and proper core structure,the magnetic coupler can improve the charging area in the case of guaranteeing enough power transfer distance.The reasonability of the method is proved by finite element electromagnetic simulation and measured dates.

Key words： Magnetic coupler core structure output power and efficiency wireless power transfer
