【摘要】：本文提出带有共模差模分离诊断功能的人工电源网络的设计与研制,可以用于测量传导骚扰电压,同时测得骚扰电压的共模分量和差模分量。文中说明网络的设计,并研制一个实物对其进行应用验证。该人工电源网络集成共差模分离网络与控制模块,集成后仍保有良好的人工电源网络阻抗与隔离度特性,与一台NNLK8821比对,测试差异最大0.49d B。共模输出时,差模分量抑制比最低为24.2d B;差模输出时,共模分量抑制比最低为25.3d B,可以提供良好的共差模诊断分析功能。经实际验证结果,本网络可以很好地测量线缆上骚扰电压,同时可有效分离出骚扰电压中的共模分量和差模分量。
[Abstract]:This paper presents the design and development of an artificial power supply network with the function of common-mode differential mode separation diagnosis, which can be used to measure the conduction disturbance voltage and to measure the common-mode component and the differential mode component of the disturbance voltage at the same time.This paper describes the design of the network, and develops a physical object to verify its application.The artificial power supply network integrates common differential mode separation network and control module. After integration, it still has good impedance and isolation characteristics of artificial power supply network. Compared with a NNLK8821, the test difference is the largest 0.49 dB.When common mode output, the lowest suppression ratio of differential mode component is 24.2 dB, and the lowest of common mode component suppression ratio is 25.3 dB, which can provide good common mode diagnosis and analysis function.The experimental results show that the disturbance voltage on the cable can be measured well and the common-mode component and the differential mode component can be effectively separated from the disturbance voltage.
