摘要
传导耦合是一种重要的串扰方式,它对导线及电缆的干扰很大。电容性耦合和电感耦合是传导耦合的两种形式,通过对它们构成机理以及原理的分析,提出了抑制它们的几种方法,如对于电容性耦合可以采用减小导线的长度、增大线间距,平衡法,对干扰源和被干扰源进行屏蔽等方式进行抑制干扰;对于电感耦合可以用减小互感,局部形成耦合环,对干扰源进行屏蔽等方式来对干扰进行抑制。
Conducted coupling is a kind of important in series interfere method, it is very large to the interference that leads line and electric cable. The electric capacity coupling matching and inductance coupling match are two kinds of forms that conducted coupling, passing the analysis to constitute the mechanism and principle to them, putting forward repressing a few of their methods： Match the length that can adopt to let up to lead line and enlarge the line to be apart from to the electric capacity coupling, equilibrium method the interference source and carrying on by the interference source to shield etc. the method carrys on repressing interference ; Can use to let up mutual inductance for inductance coupling, the part becomes coupling to match wreath, carrying on shield to the interference source etc.
