摘要

在SAE J2954、ISO 19363和IEC 61980关于汽车WPT系统标准化的现行建议中，介绍了圆形线圈和双d线圈拓扑结构。在标准化文件中，仅为两种变体指定了参考设计和耦合系数值。为了在互操作性方面比较和评估拓扑结构，本文分析了线圈系统在不对齐情况下的耦合因子容差，并定义了一个新的参数来比较系统。在第二步中，通过测量确定线圈的质量因子，以计算可实现的效率作为进一步的比较值。这些研究是针对具有相同线圈拓扑的两个系统以及具有混合线圈拓扑的两个交叉系统进行的。根据这些调查所获得的知识，可以对这四种系统在汽车WPT系统中的应用进行比较。

Comparison of Circular and Double-D Coil Topologies for Automotive Inductive Charging Systems

In current proposals of SAE J2954, ISO 19363 and IEC 61980 for the standardization of automotive WPT systems, the circular and Double-D coil topologies are introduced. Only reference designs and coupling factor values are specified for both variants in the standardization documents. To compare and evaluate the topologies in terms of interoperability, this paper analyzes the coupling factor tolerance of the coil systems in the case of misalignment and defines a new parameter to compare the systems. In a second step, the quality factors of the coils are determined by measurements to calculate the achievable efficiency as further comparative value. These investigations are conducted for the two systems with identical coil topologies on both sides as well as for the two cross-systems with mixed coil topologies. Based on the knowledge obtained from these investigations a comparison of these four systems for application in automotive WPT systems can be made.
