摘    要:针对双向电动汽车无线充电系统,对应用于双向无线电能传输的三种谐振拓扑进行了深入研究,在对其进行建模分析的基础上,结合电动汽车无线充电应用的需求特征,从对参数变化与系统故障的鲁棒性、特定工况下的最大传输功率以及谐振电容电压等方面进行了对比分析。研究表明,双边LCC谐振拓扑在继承了双边LCL优势的同时,亦解决了双边LCL传输功率偏小和直流磁化等问题,在双向电动汽车无线充电应用中具有较强的适用性。同时,搭建了相关实验平台对上述分析进行了验证。

关 键 词:无线电能传输  电动汽车  双向无线充电  谐振拓扑

Abstract:Aimed at the bi-directional wireless charging system for electric vehicles, three types of resonant topology are investigated. On the basis of modeling and analysis, the three topologies are compared with reference to the demands of electric vehicle wireless charging application, including the robustness on parameter variation and system fault, the maximum transfer power under specific operating conditions and the voltage on resonant capacitors. Studies show that LCC resonant topology while inheriting the advantages of LCL resonant topology, has also solved the problems of small transfer power and DC magnetization and so even more suitable for bi-directional wireless charging of electric vehicles. The experimental results verify the analysis. This work is supported by the Major Program of National Natural Science Foundation of China(No. 51490683).
Keywords:wireless power transfer   electric vehicles   bi-directional wireless charging   resonant topology
