摘要
接地设计是光电设备电磁兼容设计的重要组成部分,好的接地能够保护设备和人身的安全,保证光电设备正常可靠工作。地线造成电磁干扰的主要原因是它具有阻抗和感抗特性,这些特性在某些情况下会导致地环路干扰和公共阻抗耦合等电磁骚扰。从地线的特性出发分析地线干扰的成因,提出抑制地线干扰,提高电路电磁兼容性的方法。
Earthing design is an important part of EMC(Electromagnetic Compatibility)design to photoelectric equipment.Appropriate earthing could not only lead to the safety of equipment and person,but also ensure photoelectric equipment working successfully and reliably.Earthwire has the characteristics of impedance and inductance,which may bring EMI(Electromagnetic Interference)such as common empedance coupling in some situation.With the characteristics of earthwire and the cause of earthwire interference having been analyzed,some methods are put forward to control earthwire interference and improve the EMC.
