摘要: 根据等效电路模型，建立了单级螺线管型爆磁压缩发生器运行期间的电路方程，得到了回路电流表达式。采用0维电路模型计算电路参数，得到了电感和电阻计算公式。根据等效电路方程和电路参数计算公式，编写了一套计算编码，计算发生器充电过程和运行过程中发生器电路参数、内部电压、输出电流和能量、导线电导率和温度等参数的变化。与实验数据对比表明，该计算模型能准确预测单级螺线管型爆磁压缩发生器性能，对发生器的设计具有实际意义。Abstract: In this paper, an equivalent circuit calculation model of the single stage helical magnetic flux compression generators is developed. The inductance and resistance of the generator are formulated based on the assumption of zero-dimensional model. A calculation code is programmed to compute the generator parameters and the change of current, inner voltage, resistivity and temperature during the charging and operating period of the generator. The calculated results prove that the model can provide an accurate prediction for designing magnetic flux compression generators.
