摘要
鉴于电磁干扰是由电磁干扰源、耦合通路和敏感体3要素构成,因此系统的电磁兼容设计应针对此3要素展开.含TLC320AD50C的PCB构造设计通过多层去耦,地线设计为单点接地方式,并采用去耦电容等措施,很好地解决了电磁兼容问题.
The electromagnetic disturb is composed of elctromagnetic disturb source,coupling gateway and sense organ,so the design of systematic electromagnetic compatibility (EMC) should be aimed at those.By adopting multilayer eliminate coupling,designing groundwire as simple point connect earth and using eliminate coupling capacitor,the PCB structure design (include TLC320AD50C) solves the EMC problem.
