基于复杂系统的电磁兼容设计方法可行性分析

Feasibility analysis of EMC design method based on complex system

目前,电磁兼容(EMC)设计已成为复杂系统设计的一个重要组成部分,电磁兼容设计方法主要有测试分析法、经验分析法和建模仿真法三种。从日益复杂的电磁环境的要求出发,结合高度集成的复杂系统电磁兼容设计的实际困难以及电磁兼容设计人员的具体情况,分析测试分析法、经验分析法和建模仿真法这三种电磁兼容设计方法的可行性,指出三种方法的适用范围和面临的问题,从实用角度提出建立电磁兼容数据库,将电磁兼容测试数据、电磁兼容设计经验和电磁兼容模型全部入库的建议,对提高复杂系统的电磁兼容性具有现实意义。

At present,Electro Magnetic Compatibility(EMC)design has become an important part of the design of complex systems.There are three main methods of EMC design:test analysis method,empirical analysis method and modeling simulation method.Aiming for the increasingly complex electromagnetic environment requirements,combined with practical difficulties in EMC design of complex systems with high integration and the specific circumstances of EMC designers,the feasibility of the three EMC design methods is analyzed,and the scope and problems of the three methods are pointed out.From a practical point of view,a proposal to establish an EMC database for EMC test data,EMC design experience and electromagnetic compatibility model is proposed.It is of practical significance to improve the electromagnetic compatibility of complex systems.
