开关电源印制电路板EMC辅助设计的软件方法

Soft Method of PCB EMC Aid Design in SMPS

本文提出了一种基于电场分析的开关电源印制电路板EMC辅助设计的软件设计思想,即以干扰源的干扰分布图作为指导,以耦合系数为参考及时调整布线设计。文章最后给出了试验验证。

A software method of PCB EMC aid design in SMPS,based on electric field analysis,is presented in this paper.With such method, the tracks on PCB could be adjusted in time by means of interference layout of interference source and coupling coefficient.Then the experiment verification result is given.
