为了研究多导体传输线的串扰变化规律,基于传输线分布参数节点导纳法和快速傅里叶逆变换技术,推导得到了多导体传输线串扰响应的计算公式,并根据具体算例,与其他方法对比验证了本文所用方法计算结果的正确性。基于所推导公式,仿真计算并分析了干扰源上升、下降沿时间,干扰源脉宽,电缆长度以及电缆材料参数对多导体传输线串扰的影响。研究结论对于了解多导体传输线的电磁脉冲响应规律及电磁防护具有一定参考意义。
In order to research the crosstalk laws between different multi-conductor transmission line＇s core lines, crosstalk coupling voltage responses are derived based on distribution parameter node admittance method and inverse fast Fourier transform technique, then the method is validated based on an example by comparing the calculation results. Based on the derived equations, the effects of interference source＇s rising edge time and fall edge time, the pulse width of interference source, the length of cable and the material electric parameter of cable are analyzed. The results and conclusions in can be referenced in realizing the response laws of multi-conductor transmission lines to electromagnetic pulse and its electromagnetic protection.
