摘　　要：为了解决引信设计过程中,总是以实验验证方法进行电磁兼容性设计,难以通过对引信接口传导干扰的量化计算设计抑制电路的问题,提出基于引信接口紧凑模型的传导电磁干扰量化及抑制方法,用以量化分析引信传导电磁干扰,并设计干扰抑制电路。该方法以紧凑模型理论为依托,利用电感与电容的等效电路模型建立接口器件的紧凑模型,使用矢量网络分析仪测量器件实际阻抗-频率曲线,采用ADS软件,依据器件的紧凑模型进行计算,得到模型参数值,实现接口器件传导电磁干扰建模。根据所计算的模型传递函数表达式设计抑制电路,将仿真计算结果与测试结果进行对比验证,实验结果表明,该方法提出的接口传导电磁干扰模型及抑制方法能够真实反映器件高频信号传导特性,能够对不同外注干扰信号通过接口器件的传导干扰的量值进行计算和抑制,抑制电路达到干扰噪声抑制效果,为引信电磁兼容设计奠定基础并提供数据支持。In order to solve the problem of always using experimental verification methods for electromagnetic compatibility design in the process of fuze design,which is difficult to design suppression circuits through quantitative calculation of conducted interference at the fuze interface,a conducted electromagnetic interference quantification and suppression method based on the compact model of the fuze interface was proposed to quantitatively analyze the conducted electromagnetic interference of the fuse and design interference suppression circuits.Based on the compact model theory,this method used the equivalent circuit model of inductance and capacitance to establish a compact model of the interface device.A vector network analyzer was used to measure the actual impedance frequency curve of the device,and ADS software was used to calculate the model parameter values based on the compact model of the device,achieving the modeling of conducted electromagnetic interference in the interface device.A suppression circuit based on the calculated model transfer function expression was designed.The experimental results showed that the interface conducted electromagnetic interference model and suppression method could truly reflect the high-frequency signal transmission characteristics of the device,and calculate and suppress the amount of conducted interference of different external injection interference signals through the interface device,and the suppression circuit could achieve interference noise suppression effect.
