摘　　要：以往的电路板设计,往往是电路板完成后,经过电磁兼容标准测试未通过,再返回进行整改,实践证明,这种方法效果非常有限,而且要花费大量时间和精力.介绍基于偶极子模型的共模辐射机理,利用EMSCAN系统对控制器进行扫描,总结出了一套辐射发射诊断方法,在电路板设计过程阶段即可反复进行电磁兼容预测试,该方法经验证具有很高的可行性.The previous method of designing the circuit board is that,after completing the circuit board,and failed the EMC standard test,then returned to the rectification.This method has much limited effect.What＇s more,it asks for much time and vigor.Through introducing the EMI theory based on electric dipole modle,and scanning the controler by utilizing EMSCAN system,the paper summarized an EMI diagnosis method.Then,the EMC pretest can be done repeatly while the stage of circuit board design.The method proved high feasibility.
