A compact SCR model using advanced BJT models and standard SPICE elements

一种基于双极型晶体管的 SCR 集约模型



基于双极型晶体管和标准SPICE器件提出了一种可控硅整流器 (SCR) 的集约模型。 为解决晶体管模型中弱击穿模型难以仿真过压击穿的问题, 在双极型晶体管基础上增加了基于电阻二极管组合的P-N结击穿模型, 实现了在无瞬态效应下SCR负阻特性的模拟; 考虑到寄生双极型晶体管集电极电流对SCR内部电阻的影响, 建立了阻值依赖SCR开启状态改变的可变电阻模型。 最后, 利用传输线脉冲测试和直流测试结果对模型有效性进行了验证。
