摘要
从通信电子系统的EMC标准与要求出发,对系统中的开关电源电磁干扰机理进行分析,并以某型号通信系统的开关电源电磁兼容性试验为例,通过对开关电源内部干扰抑制、外部干扰抑制、元器件布局、布线等方面进行设计分析,阐述了开关电源EMC设计思路、解决方法和注意事项。
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.
