【摘要】：本文提出帶有共模差模分離診斷功能的人工電源網(wǎng)絡(luò)的設(shè)計與研制,可以用于測量傳導騷擾電壓,同時測得騷擾電壓的共模分量和差模分量。文中說明網(wǎng)絡(luò)的設(shè)計,并研制一個實物對其進行應(yīng)用驗證。該人工電源網(wǎng)絡(luò)集成共差模分離網(wǎng)絡(luò)與控制模塊,集成后仍保有良好的人工電源網(wǎng)絡(luò)阻抗與隔離度特性,與一臺NNLK8821比對,測試差異最大0.49d B。共模輸出時,差模分量抑制比最低為24.2d B;差模輸出時,共模分量抑制比最低為25.3d B,可以提供良好的共差模診斷分析功能。經(jīng)實際驗證結(jié)果,本網(wǎng)絡(luò)可以很好地測量線纜上騷擾電壓,同時可有效分離出騷擾電壓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.
