通信电源设备电磁兼容问题的诊断与处理

Diagnosis and Solutions for the EMC Problem of the Telecommunications Power Supply Equipment

文章简要介绍了我国通信电源现行的电磁兼容测试标准;分析了通信电源设备在电磁兼容方面容易出现的技术问题;提出了常用的诊断和解决方法。并通过选取某一款通信用高频开关电源模块进行了实验室测试与分析。试验环境:美国ETS高性能屏蔽室、标准3米法电波暗室;瑞士Shaffner EMC测试系统。最后对高频开关电源模块的EM I/EMS问题给出了具体的诊断与解决方案。

This paper introduced EMC measure standards of the Telecommunications Power Supply Equipment（TPE） in briefs, analyzes and introduces the methods about how to diagnose and resolve the EMC problems of the TPE. BY testing some ＂High Frequency Switching Mode Power Supply for Communications＂ in the environment of ＂American ETS Company high ability shielding room, Standard 3 m electromagnetism darkroom, Switzerland Shaffner EMC testing system＂. At last, the paper gives the concretely diagnosis and detailedly resolvents about TPE＇s EMI/EMS problem.
