INTRODUCTION TO CONDUCTED EMISSION By Duncan FUNG 18 April 2015 ieee EMC Chapter - hong kong Section EMC Seminar Series - All about EMC Testing and Measurement Seminar 2 TOPICS TO BE COVERED Background on Conducted Emission Equipment and Test Setup TYPES OF EMISSION FROM ELECTRICAL AND ELECTRONICS APPLIANCES Radiated Enclosures Conducted Power port (AC/DC) Signal/ control port Telecommunications / Network Port (CAT5, 6) To Victims ( other ITEs) through mains network or extension cords. Switching noise from SMPS Digital noise WHY WE NEED TO DO CONDUCTED EMISSION TESTS? Conducted emission refers to the mechanism that enables electromagnetic energy to be created in an electronic device and coupled to it mains or telecommunications ports. Standardization bodies ( CISPR, IEC) had set out the allowable conducted emissions from electronics devices, and stated the limits in various standards ( product standards, generic standards).
