摘　　要：针对现阶段大量的传导性电磁干扰问题仍不断出现且尚未得到很好地解决的现象,对传导性电磁兼容进行了综合技术研究,提出传导性电磁干扰噪声诊断与抑制一体化的智能处理系统,将软件设计与硬件设计相结合,对噪声进行相应的处理.同时对传导噪声智能处理系统进行参数建模,给出将技术解决方案与经济成本优化联系在一起的综合数学模型和设计指导方法.同时给出建模后的测试装置和相关实例,并对实际测量的数据进行了实验对比,结果表明该系统能有效解决电源线上的EM I噪声的干扰问题.As most problems of the conducted EMI noise is not solved so perfectly, the paper presents an intellectual system of conducted noise diagnosis and suppression. The system is consisted of software and hardware, aims to dealing with the noise properly. Research on parameter-modeling of the intellectual system is done. It presents a mathematical model and design guidance both technically and economically. The paper also gives the test setup and an example. The experimental results show that this intellectual system is efficient in solving electromagnetic noise on the power line.
