摘要
实验研究了双指数电磁脉冲场对数字式微控制器形成干扰的特点,通过比较两种不同波形参数的电磁脉冲在形成临界干扰时的异同,分析了不同波形参数对干扰阈值的影响,进一步明确了电磁脉冲对微控制设备干扰的形成并不只是由干扰场的幅度指标决定,并通过多次实验确定了脉冲上升沿的陡度对干扰阈值的决定作用。
The interference characteristics of double exponential EMP on DDC device of the switch cabinet are studied. EMPfield with two typical waveforms were compared to observe the change of interference threshold under different EMPwaveforms. It is shown that the forming of interference relates with both the peak value and the rising time of the EMP.
