摘　　要：三线圈感应耦合电能传输(ICPT)系统在给定工作频率下,中继线圈与原级线圈、负载线圈间的互感及负载大小是影响系统电能传输效率的主要因素。针对线圈间互感与线圈位置的相互约束关系,提出一种在任意给定原级线圈和负载线圈条件下的中继线圈位置优化模型。该模型以电能传输效率为优化目标,综合考虑三个线圈相互间的互感和负载等参数,通过计算机辅助设计,解决了寻找中继线圈最优位置的问题,理论和实验结果具有较好的一致性,且展示出中继线圈的最优位置与负载大小密切相关。As for the 3-coil inductively coupled power transfer system （ICPT） , in the given frequency, themutual inductance between relay and primary coils, the mutual inductance between relay and load coils, and theload are the main factors that affect the efficiency of power transmission. By considering themutual inductancesbetween the coils and the constraint relationship of the coil location, an optimization model of the relay coillocation with the arbitrarily given primary and load coils is proposed. With the power transfer efficiency as theoptimization objective, this model considers the mutual inductances of the three coils, the load, and otherparameters. The relay coilJ soptimal location problem is then solved with compter aided design. Experimental results arewell consitent with theoretical analysis. The optimal location of the relay coil is closely related to the load.
