| 摘 要： | 采用了计算注入干扰下电缆网络节点响应波形的时域电磁拓扑求解方法。在传输线SPICE模型和电缆网络节点SPICE模型的基础上,通过SPICE软件求解电缆网络时域响应波形,该方法可以简化传输线网络时域响应波形求解的过程。为验证方法的有效性,建立简单的传输线网络,并将传输线网络转换成SPICE网络,通过SPICE模拟计算处在注入干扰下各电磁网络节点处的电磁响应波形,利用方波噪声源进行实验,对两个选定网络进行脉冲注入。实验表明,所述方法与实测数据有较好的一致性,当传输线均匀时,影响传输线网络响应波形的因素主要有:(1)传输线中的时延;(2)传输线网络节点上的反射。

| Abstract: | A time domain topological analysis method to compute response waveform in each node of cable network was introduced,which was injected with electromagnetic pulse.Based on SPICE model of transmission line and nodes of cable network,SPICE was used to compute the response waveform of cable network in time domain.Two simple transmission line networks were provided to convert them into SPICE networks with SPICE to compute.To validate the method,an experiment with rectangle pulse implemented on the two simple net... |
