EMC design is an important content of product design, and CE102 conduction emission is one of the im-portant items in the EMC design of equipment and subsystem products. Taking portable control device as the research object, the design and research of CE102 of EMC is carried out. By adding a power line filter to the input end of the power supply, the insertion loss is effectively increased in a limited space and the purpose of power line filtering is achieved. The validity of the above design method is proved by the test results, and the research has reference sig-nificance and value for developing EMC design of products.
