摘　　要：为预测电子设备传导敏感度试验中脉冲电流注入在设备端口产生的干扰强度及波形,建立了感性电流注入装置的SPICE(Simulation Program with Integrated Circuit Emphasis)电路模型.在将装置电路模块化的基础上,应用传输矩阵计算的方法,从实验数据中提取出各模块的电路参数或方程表达式,并转换为SPICE模型,最后再将各模块组合为完整的装置模型.频域和时域的实验显示,模拟结果和测量结果一致性较好.建立的电路模型可用于设计和优化脉冲电流注入试验.In order to predict the interference pulse entering the equipment in conducted susceptibility testing, a SPICE （Simulation Program with Integrated Circuit Emphasis） model of pulsed current injection（PCI） is developed. Firstly, after the whole circuit is decomposed into various modules, circuit equations are derived from the measurement data with the method of transmission matrix calculation. Then each module is expressed by SPICE model. At last, the complete model is assembled with subcircuit models. The modeling result is identical to the measurement in validation experiment. The SPICE model can be used to design and optimize PCI tests.
