摘要
在分析差动平衡法和极性鉴别法抗电磁干扰性能的基础上,提出了定向耦合差动平衡法;论述了该方法的基本原理和特点;通过模拟和带电试验,分析了该系统的线性度和抗干扰能力,从而证明了这种方法的有效性及应用前景。
This paper presents the directional difference balance method(DDB) according to the analyzing the property of suppressing electromagnetic interference either with difference balance method or polar discrimination method.The fundamental principle and characteristic of DDB method is discussed in detail.Linearity and suppressing noise property of the system is analyzed so that its efficiency and application prospect is proved.
