摘　　要：随着各种电子产品的广泛问世,大量的传导性电磁兼容问题不断出现且尚未得到很好地解决.针对传导电磁兼容中的一些关键技术进行了系统研究,包括通过对传导EMI噪声分离技术对比分析,进行了EMI噪声诊断实验与仿真研究,并提供了噪声抑制与滤波器设计方案;为得到有效的噪声抑制效果,介绍采用双电流探头和希尔伯特变换获取噪声源内阻抗信息;并提出了基于技术与经济一体化的传导电磁兼容决策阐述建模,还给出了EMI噪声抑制及噪声源内阻抗测定的相关实例,以验证方法的有效性.With the development and come out of various kinds of electronic products, a lot of problems about conducted EMC have appeared but havent been perfectly solved yet. This paper makes a systematic study on some key techniques in conducted EMC, including a contrastive analysis of conducted EMI noise separation techniques, conducting a diagnostic experiment and simulation study of EMI noise, providing a design plan of noise suppression and filters. In order to get an effective result of noise suppression, the paper introduces the way of obtaining impedance information of noise source with two probes approach and hilbert transform, suggests a decision making model built based on combination of technic and economy, and illustrates the validity of the method with the examples of EMI noise suppression and measurement of noise source impedance.
