摘　　要：依据脉冲放电电路的等效电路及其微分方程,采用Levenberg-Marquarat算法对主电容放电电压测试波形数据进行衰减系数识别,从而获得模拟电流波形。该方法克服了分流器法和Rogowski线圈法等直接测量小型高压引爆装置冲击电流时,因附加电路引起的电流波形失真。MATLAB模拟结果表明,该方法得到的电流模拟波形与真实电流波形拟合精度高,可用于直列式引信电子安全与解除保险装置和低能冲击片雷管的优化匹配设计。A simple method was developed for measuring the impulse current waveform produce by a small high-voltage exploding device. The model of impulse current was determined by attenuation co- efficient. To estimate the attenuation coefficient from the actual discharge voltage curve, the Leven- berg-Marquarat algorithm was applied based on the equivalent circuit of discharge circuit and its dif- ferential equations. Compared with the direct measuring methods such as using shunt or Rogowski coil, this method overcomes the distortion of impulse current waveform caused by additional measur- ing circuit. The results show that the simulation current waveform fits the actual current waveform well. The method can be used for optimum matching design of electronic safety, arming device of in- line fuse or low-energy slapper detonator.
