SCHWARZBECK 人工电源网络汇总
特征:
●为被测设备(EuT)提供必要的电源电压(AC或DC)和电流
●耦合由EuT产生的干扰电压并将其提供给接收器
●为被测设备(EuT)提供明确的射频阻抗
●防止来自电源(滤波器)的不必要干扰
●保护电源免受EuT产生的不必要干扰电压的影响
●我们可以区分三种类型的LISN:V型、T型和德尔塔型LISN

V-LISN分别测量两条线路L1和地之间或L2和地之间的不对称干扰电压。V-LISN也称为V-ANM(人工干线网络)。V-LISN是迄今为止最常用的LISN。
有两种类型的V-LISN具有不同的阻抗。具有5μH电感的V-LISN(CISPR 16-1-2、CISPR 25、ISO 7637、DO160)通常用于测量连接到直流或400 Hz机载电源的车辆、船只和飞机的设备。根据CISPR 16-1-2、MIL STD 461和ANSI C63.4,具有50µH的另一种类型的V-LISN旨在在50 Hz或60 Hz的电源频率下运行。
T-ISN(图2右侧)测量不对称干扰电压(共模电压),并将其提供给EMI接收器。T-ISN通常用于测量连接到对称线路(如双绞线)的电信和数据传输设备。
