摘要
Abstract
Switching power supply,as a electromagnetic interference (EMI) source,is widely used in power electronic equipments. The EMI filter should be prepositioned in power circuit design to suppress the conducted EMI. CE102 is taken as a project of EMC tests to detect the conducted interference of power-line. It is a necessary measuring project of electronic equip-ments,especially for military electronic equipments. It means that the design of the power system fails if the interference ex-ceeds the standard. An EMI filter was designed to find and solve the problems of the design by CE102 test and analysis. The ef-fectiveness of the design was proved by CE102 after the test validation.关键词
