| 摘 要： | 电磁干扰(EM I)噪声发射一直是电磁兼容(EMC)学科面临的重要问题,而EM I电磁干扰噪声的测量将直接影响到噪声抑制的结果.提出了基于独立分量测量方法的EM I电磁干扰噪声分析和抑制解决方案,介绍了独立分量测量方法的原理和EM I噪声处理软件平台,通过对传导噪声进行特征提取和模态分析,为噪声抑制及电磁兼容综合解决方案提供必要信息.对开关磁阻电机构成的风机调速系统进行传导电磁兼容测试,并对试验数据进行了对比和分析,结果表明该方法能有效分离出EM I噪声中的各模态分量.

| Abstract: | Electromagnetic interference(EMI)is one of important issues in electromagnetic compatibility(EMC)engineering and how EMI noise measurement is done will directly affects the noise suppression results.In this paper an improved EMI noise solution scheme is proposed that differs on presenting an intellectual and unified idea to make noise independent component measurement in conjunction with noise analysis and noise suppression.The principle of independent component measurement and intellectual noise processing software are studied.Also noise characterization and mode analysis are implemented for noise mitigation and future EMC solution scheme.Moreover,EMC experiment for switched reluctance motor(SRM) drive system is conducted to show the efficiency of new method developed in this paper. |
