摘　　要：目前感应式无线电能传输(inductive power transfer,IPT)系统电磁耦合机构的设计往往是追求单目标或者是多随机目标的设计准则,这导致了电磁耦合机构设计的非全局性优化品质问题。针对该问题,文章首先提出电磁耦合机构的携能特性指标、空间特性指标及能效特性指标作为其综合性能评判的指标体系,在此基础上引入模糊综合评判方法,提出一种电磁耦合机构综合性能评判方法,对满足同一应用需求的多种类型电磁耦合机构进行评价,并得到具体、直观的数值评价结果,为耦合机构类型的确定提供参考。文章对以电动汽车无线充电系统的电磁耦合机构为例,通过层次分析法推导得到具有目标权重的性能特性指标的表述,并应用提出的评判方法对两种类型电磁耦合机构的综合性能进行评判,得到具体的数值评判结果。最后通过实验验证理论分析的合理性。Recent researches show that only a single objective or even stochastic objectives are considered in the traditional magnetic coupler design for IPT systems, thus global optimum failed to achieve while researching the performance characteristics of magnetic couplers. In this paper, first, in order to evaluate different types magnetic couplers with scientific considerations, a novel index system which composed by power storage capacity characteristic index, spatial characteristic index and output power and efficiency characteristic index were discussed to evaluate the overall performance of magnetic couplers, then, and an evaluation method was proposed based on the index system. Analytical expressions for those three performance characteristics were obtained with the Analytical Hierarch Process（AHP） method, and then a Fuzzy Comprehensive Evaluation（FCE） method was introduced to evaluate the following magnetic coupler designs for EVs＇ wireless charging systems, a numerical matrix was obtained which can intuitive evaluating the performance characteristics of a magnetic coupler. Finally, experimental results verified the rationality of theoretical analysis.
