摘要
介绍了在EWIS设计活动中,相关电磁兼容性考虑的各关键因素,根据电磁兼容基本理论,通过电磁仿真,分析了互联线缆的分类、布线、线型、结构,以及接地方式等影响,提出EWSI电磁兼容正向设计优化的思路。指出了在电气互联领域一些错误的理念和做法,并提出实现有效抗扰的理念。
The key factors considered by Electromagnetic Compatibility( EMC) in Electrical Wiring Interconnection System( EWIS) design process are introduced. Based on the basic theory of EMC,the influence of the cable category,cabling,cable type,cable structures and grounding way on the EMC are analyzed by the simulation. And the top-down design optimization approach of EMC in the EWIS is proposed. Some wrong opinions and practices in the field of EWIS are pointed out and the effective anti-interference theories are proposed.
