一种通信电源模块传导骚扰测试的改进方法

An Alternative Certification Method for Conducted Emissions of SMPS

针对TD-LTE通信基站设备电源端口传导骚扰测试时开关电源模块单体能通过测试，但基站设备不能通过测试的情况，对比分析了其产生的原因，并提出了一种电源模块传导骚扰测试的改进方法。实测结果证明，该方法能够大幅降低电源模块和基站设备传导骚扰测试结果的差别。

In this paper, the reasons why switching mode power supply （SMPS） for TD-LTE base stations alone could pass the conducted emissions （CE） test while the whole equipment could not are analyzed. An alternative certification test method for conducted emissions of SMPS is proposed. Test results prove that this method can greatly decrease the difference between test results of single SMPS and base station equipment.
