| 摘 要： | 介绍了脉冲强磁场模拟器的工作原理, 将微型计算机置于脉冲磁场模拟器中，通过改变脉冲磁场的幅度和上升时间，研究脉冲磁场对微电子设备的干扰途径、干扰阈值与脉冲上升时间、脉冲宽度的关系。试验结果表明，微电子设备的连接电缆是脉冲磁场干扰引入的主要途径；简单的屏蔽措施对于脉冲磁场干扰有一定的抑制作用；脉冲磁场的时间变化率越大，对微电子设备的干扰作用越强。

| Abstract: | A pulsed magnetic field simulation system was developed to study the effect of micro-electronic system under strong magnetic pulses. In the experiment, personal computers were put into the electromagnetic environment of the simulator. Coupling paths, interference threshold, the relation of the threshold with rising time and duration time of the field were studied by changing the peak value, duration time and rising time of the simulated pulsed magnetic field. Results show that the connecting cables are the main paths that introduce interference, simple shielding can reduce the interference at some extent, and the interference is more potential to affect the micro-electronic system if its time derivative is larger. |
