摘　　要：将电路仿真软件用于半导体桥火工品的电磁兼容性设计时,仿真准确程度取决于发火电路和半导体桥器件模型的精度。通过在电路软件中建立电容放电发火电路和半导体桥火工品电子器件模型来实现半导体桥的电爆过程仿真。研究结果表明:在电容放电发火仿真电路中,当回路电感为0.62μH、回路电阻为3.3 mΩ时,仿真电路可用于模拟实际电容放电发火电路;对比半导体桥火工品爆发过程的仿真和试验结果发现,子电路建模方法建立的半导体桥器件模型能够有效模拟出半导体桥的电爆特性曲线,且模拟电爆参数均在误差范围内。When circuit simulation software is used for the electromagnetic compatibility design of the semiconductor bridge(SCB)initiator,the accuracy of the simulation depends on the accuracy of the firing circuit and semiconductor bridge device model.A capacitor discharge ignition circuit and a SCB initiator electronic device model were established in the circuit software to achieve the simulation of the electro-explosive process of the SCB initiator.The results show that,in the simulation circuit of capacitor discharge and ignition,when the circuit inductance is 0.62μH and the circuit resistance is 3.3 mΩ,the simulation circuit can be used to simulate the actual capacitor discharge and ignition.After comparing the simulation and experimental results of the explosion process of SCB initiator,it is found that the SCB initiator model established by the subcircuit modeling method can effectively simulate the electro-explosive characteristic curve of the SCB,and the simulated electro-explosive data are all within the error range.
