电动汽车车内电磁辐射的仿真分析研究
|
摘要
为了研究汽车外壳表面电流产生的电磁干扰(EMI),基于界面条件理论和趋肤效应,提出了以电动汽车供电系统电磁辐射(EMR)表面电流为例的仿真方法。随后在HFSS软件中建立电动汽车供电系统发射模型,最后,模拟分析了表面电流密度分布及其对辐射场的影响,分析结果表明,增加电动机电阻和引线电阻可以有效抑制供电系统辐射噪音,同时增加绕线电阻和电感可以加强抗干扰能力,本研究为汽车电磁兼容(EMC)的设计提供重要的参考。
In order to study the electromagnetic interference (EMI) generated by the surface current of the car shell,based on the interface condition theory and the skin effect,a simulation method is proposed on the electromagnetic current (EMR) surface current of the electric vehicle power supply system. Subsequently,the electric vehicle power supply system emission model was established in the HFSS software. Finally,the surface current density distribution and its influence on the radiation field were simulated and analyzed. The analysis results show that increasing the motor resistance and the lead resistance can effectively suppress the radiation noise of the power supply system,and increase simultaneously. Winding resistance and inductance can enhance the anti-interference ability. The research provides an important reference for the design of automotive electromagnetic compatibility (EMC).
