摘要
接地技术是防止电磁干扰、增加电子设备电磁兼容能力、提高设备可靠性的重要方法之一。但是,如果接地不当就会引入电磁干扰,影响电路或系统的正常工作。通过对接地中的地环路干扰的分析,阐述四种抑制地环路干扰的技术措施:使用浮地方法、引入隔离变压器、引入纵向扼流圈以及引入光电耦合器。
The grounding technique is one of the important methods which can prevent the electromagnetic interference and enhance the electromagnetic compatibility and reliability of electronic equipment.But the electromagnetic interference caused by unsuitable grounding will influence the normal operations of circuits or systems.After a analysis on the earth loop interference of grounding,this paper expounds four kinds of technical methods which can restrain the earth loop interference:using floating ground,isolation...
