摘要 随着电动汽车以及自动驾驶技术的推广,大量电子电气设备的使用对电磁兼容(EMC)提出了日趋严苛的要求,产品设计中的EMC问题变得越来越重要。该文对主电路分单纯铺铜、增加铁质连接片以及增加铁质连接片与铜质导线三种情况分别建立有限元模型,计算得到了表面电场强度,分析了电场分布趋势。通过实验测量风扇电机控制电路和主电路的电磁场分布。实验结果证明仿真结果的正确性,进而分析局部电场强度集中的原因,给出改进措施。对控制电路主芯片连接MOSFET栅极的信号网络进行信号完整性分析,仿真计算得到了线路眼图,通过调整终端电阻,改善了眼图的眼高和眼宽,有效地提高了信号的传输质量。通过主电路的有限元分析和控制电路的信号完整性仿真,精确地研究了电场强度和线路眼图,相比传统的定性分析方法,给出了更加准确的电子电路改进措施。

Abstract:With the popularization of electric vehicles and autonomous driving technology, the use of amount of electronic and electrical equipment has put forward increasingly stringent requirements for electromagnetic compatibility (EMC), and the EMC problem in product design has become increasingly important. In this paper, the finite element model is established for the main circuit, including the simple placing of copper, the addition of iron connectors, and the addition of iron connectors and copper conductors. The surface electric field intensity is calculated and the electric field distribution trend is analyzed. The electromagnetic field distribution of fan motor control circuit and main circuit is measured by experiments. The simulation results are proved to be correct, and the reason of local field intensity concentration is analyzed, and the improvement measures are given. The signal integrity analysis of the signal network connecting the MOSFET grid electrode with the main chip of the control circuit was carried out, and the line eye diagram was obtained by simulation calculation. By adjusting the terminal resistance, the height and width of the eye diagram were improved, and the transmission quality of the signal was effectively improved. Through the finite element analysis of the main circuit and the signal integrity simulation of the control circuit, the field strength and line eye diagram are accurately studied. Compared with the traditional qualitative analysis method, more accurate electronic circuit improvement measures are given.
