摘　　要：针对传统抑制共模干扰的方法存在着成本高、电路复杂的缺陷,从共模干扰的概念入手,认真分析了共模干扰产生的原因,并在此基础上,提出了一个低成本高效率的解决电路。The traditional suppress common mode interference method is mostly used transformer isolation, isolation, but inevitably there is a high cost, complex circuit defect. This article from the start with the concept of common mode interference, a careful analysis of the common mode interference causes, and combined with graphics by mathematical formula image illustrates the common mode voltage size, on this foundation, put forward a low cost and high efficiency to solve circuit.

关 键 词：两线制 平衡总线 共模干扰 虚拟隔离
