电源适配器的传导骚扰超标案例分析

Case Study on the Conduction Disturbance of Power Adapter

近年来,电源适配器越来越广泛应用于很多领域。但是在设计初期,电源适配器在做验证时,若对电磁兼容的设计考虑不周,往往会导致其不能满足电磁兼容要求,有时处理起来需花费非常多的时间。主要针对一款应用于IT产品的电源适配器的传导骚扰对策案例进行分析,提出在产品研发前期,一定遵循电磁兼容设计的原则,方可满足相关的电磁兼容要求。

In recent years,the power adapter is more and more widely used in many fields,but at the beginning of the design,the power adapter in the verification,if the design of electromagnetic compatibility is not considered,often lead to its failure to meet the requirements of electromagnetic compatibility,sometimes to deal with the need to spend a lot of time.This paper mainly analyzes the case of a power adapter applied to IT products,and proposes that in the early stage of product development,the principle of emc design must be followed to meet the relevant emc requirements.
