开关电源的电磁兼容设计

The design of electromagnetic compatibility of switching power supply

近年来,电磁兼容技术已成为现代电子系统工程设计中的重要组成部分。开关电源是电子系统中主要干扰源之一,如何提高它的电磁兼容性问题显得越来越突出。本文主要从几个方面讨论了开关电源电磁兼容设计要注意的问题。

In recent years, the technology of electromagnetic compatibility has become an important part in the engineering design of modern electronic systems. The switching power supply is one of the major jamming sources in the electronic systems, and the problem of improving electromagnetic compatibility is becoming more and more prominent. Some issues to be noted about the design of electro- magnetic compatibility of switching power supply are discussed from several aspects in this paper.
