为了降低冲击片雷管起爆能量，优化高压脉冲功率源等效参数，研究了高压脉冲功率源等效参数如等效电感、等效电阻、电容量、电压等参数对金属桥箔电爆特性规律的影响，测试了金属桥箔在不同的等效参数条件下，其电爆性能的变化规律参数，计算了金属桥箔的能量利用率，实验结果表明：当高压脉冲功率源储能电容容量为0．2μF，放电回路等效电感为57 nH，等效电阻为68 mΩ时，在加载电压为2．0 kV放电条件下，桥区厚度为5．0 μm，尺寸为0．5 mm×0．5 mm的铜箔其爆发性能最优，有效能量利用率达到最高，为54．8％，此时桥箔的爆发时间与峰值时间最为接近，时差最小。

In order to reduce the ignition energy of exploding foil initiator( EFI),and optimize the performance and the parameter of high voltage pulse power source,and the effects of the high voltage pulse power source equivalent parameter on the exploding per-formance of the foil bridge were investigated with 0. 5mm×0. 5mm×5. 0μm copper foil bridge. By calculating the performance pa-rameter including the equivalent inductance,equivalent resistance,capacitance of pulsed power capacitor and load voltage ac-cording to the oscillation waveform parameters from the experimental,the energy efficiency was obtained,and the change rules were studied. Results show that when the capacitance is 0. 2 μF,equivalent inductance is 57 nH,the equivalent resistance is 68 mΩ and the load voltage is 2. 0 kV of high voltage pulse power source,the exploding performance of the foil bridge is the best, that energy efficiency is 54. 8%,reaching the highest,and the time difference of the burst time and the peak time are the shortest.
