摘要
介绍电动汽车感应充电系统松耦合变压器的特性,通过Ansoft有限元分析软件对松耦合变压器进行仿真分析,结合简化磁路模型和磁力线分布,得出大气隙下的EE磁芯的精确模型。结合精确模型和模拟结果,给出横截面积对耦合系数的影响,实际制作变压器,测量发现,面积增加,耦合系数得到提高,输出电压能力增强,为松耦合变压器的优化设计和进一步实验提供理论指导和参考。
The characteristics of loosely coupled transformer for inductive charging system of electric vehicle were analyzed, After simulations and detailed analysis of the transformer which were carried out by Ansoft, and through the magnetic circuit analysis, the influences of gap on the loosely coupled transformer inductive and coupling performances were studied. Then, through the experiments, compared with simulated results, it verify the impact of cross section area on the transmission efficiency, making transformers, finding that if the cross section area doubled, the coupling coefficient increased and the output of Voltage increased. The results are helpful and give some theoretical guides and references for the further optimized.
