| 摘 要： | 通过等效电路方法计算了MA量级小型螺线管爆磁压缩发生器(HEMCG)各参数,得到发生器的损耗主要来自非欧姆损耗。设计的HEMCG整体外径约140 mm,长度小于550 mm,初始电感128.7μH。实验表明,在初始电流3.6 kA条件下,在100 nH负载上输出前沿75.2μs、峰值1.87 MA的电流脉冲,电流放大约519.4倍,能量放大约209.5倍,炸药化学能到电磁能的转换效率为6%。两发HEMCG分别经原边电感约440 nH、副边电感约4μH、耦合系数约0.85的电缆变压器调制,在4μH负载上得到了上升时间约80μs、峰值72 kA的脉冲电流,变压器能量传输效率约为26.8%。

| Abstract: | The parameters of miniature MA-level helical explosively-driven magnetic flux compression generator(HEMCG) are calculated by method of equivalent circuit，and the result indicates that the main loss of HEMCG is non-Ohmic loss．The entire outer diameter of HEMCG with initial inductance of 128.7 μH is about 140 mm，and the length is less than 550 mm．When the initial current injected is 3.6 kA in the experiment, a pulse current with 75.2 μs risetime and 1.87 MA peak value is obtained on the 100 nH load while the seed current is amplified by 519.4 times，which means that the energy amplification coefficient is 209.6，and the conversion efficiency from chemical energy of explosive to electromagnetic energy is 6%．The HEMCG is modulated by cable transformer with about 440 nH primary inductanc |
