| Abstract: | According to EMC （Electro Magnetic Compatibility） standards and requirements of the electronic communication systems, the electromagnetic interference mechanism of switching power supply in these systems is analyzed. The EMC test of switching power supply in a certain communication system is taken as an example, and then EMC design ideas, solutions and matters needing attention are illustrated by the analysis of internal interference suppression, external interference suppression, component layout and component wiring of switching power supply. |
