摘要

本报告分析了发电机、电动机和电池之间的共模电流回路及其对辐射发射效应的影响。由于现代车辆电气和电子系统的复杂性日益增加，开发周期日益缩短，因此通过电磁仿真对虚拟原型进行设计研究是必要的。我们展示了一种自动化数值网格生成的新方法，该方法避免了手工工作，并显着减少了准备操作的总时间。最后，我们论证了共模电流回流路径在车辆中的影响，并解释了抑制排放的对策。

Emission Reduction by Optimizing Current Return Paths in Electric Vehicles

This presentation deals with the analysis of common mode (CM) current return paths between the electric generator, the electric motor and the battery cells, and their impact on radiated emission effects. Due to the increasing complexity of electrical and electronic systems in modern vehicles and the ever-shorter development cycles it is essential to run design studies on virtual prototypes by means of electromagnetic simulations. We demonstrate a new methodology for an automated numerical mesh generation that avoids manual work and significantly reduces the total time for preparatory operations. Finally, we demonstrate the effect of common mode current return paths in vehicles and explain countermeasures in order to suppress the emission.
