EMC设计中的辐射发射指标分解

Decomposable Method of Radiated Emission Limit in EMC Design

随着电磁兼容(EMC)设计系统法的逐步推广,在设计过程中就必须对电磁兼容的一些指标进行分解。依据分解指标在系统设计中进行指标控制,设计初期就各分系统、各单元、各单板逐层进行EMC控制。本文就此介绍了一种电磁兼容中辐射发射项目的分解方法,对其实用性进行了分析,同时给出其控制辐射发射指标的设计要点。

With EMC(electromegnetic compatibility)systems approach widely being used,limits have to be decomposed in EMC design and gain decomposed specification.In initial design stages,EMC situation of every subsystem,every unit or every PCB board can be controlled in process of EMC design according to decomposable limit.In this paper,a decomposable method of RE limit is presented,and practical application of this method is analyzed.The same time design points of RE also be given in this paper.
