摘要

一个汽车系统级大电流注入(BCI)装置的小信号模型是用先前出版物中显示的广义精确方法开发的，并在一个示范EUT模块的案例研究中得到验证。该研究对浮动不接地的EUT板采用等效电路建模方法，对有源DUT IC采用宏模型。利用IC故障阈值和BCI测试下浮动EUT模块射频电平的小信号模拟，对BCI测试结果进行了基于仿真的预测。由于BCI设置模型的高精度和细节性，预测结果也显示出与实际测量数据非常好的相关性，无论是定性还是定量，最高可达1ghz。

Experimental validation of the generalized accurate modelling method for system-level bulk current injection setups up to 1 GHz

A small-signal model of an automotive system-level bulk current injection (BCI) setup developed with a generalized accurate method shown in the previous publication is verified on a case study with a demonstrator EUT module. The work utilizes an equivalent circuit modelling approach for the floating ungrounded EUT board and a macromodel for an active DUT IC. The simulation-based prediction of the BCI test results using an IC failure threshold and a small-signal simulation of RF levels at floating EUT module under BCI tests is shown. Due to high accuracy and detail of the BCI setup model, the prediction also shows very good correlation to real measurement data, both qualitatively and quantitatively, up to 1 GHz.
