| 摘 要： | 汽车点火系统工作时产生的电磁干扰具有能量大,频带宽等特点,被认为是汽车电磁兼容最主要的电磁干扰源。笔者提出了一种预测点火系统传导电磁干扰模型建立方法:建立系统中每个部件的电路模型,利用测量、解析法或有限元方法确定模型中的分布参数,集成为点火系统等效电路模型进行系统仿真计算。时域与频域实验测试结果证实了该模型的正确性与方法的可行性。

| Abstract: | The ignition system in automobiles is a main source of electromagnetic interference(EMI),because the electromagnetic emission from the system has the characteristics of high-energy and wide-bandwidth.A method for EMI prediction based on its components' circuit models is presented.First,the characteristics of the components are analyzed and the equivalent circuits are drew;then,the parasitic parameters of the electromagnetic device are extracted from measurement,analytical solution or finite element method(F... |
