摘要
一种由蓄电池作为初始能源的紧凑型螺线管爆磁压缩发生器由两级构成,其中第一级作为能量放大器,第二级通过磁通耦合对第一级输出的脉冲进行陡化以驱动较大的电感负载.初始能源由蓄电池、高压逆变器及储能电容器(220 μF, 6 kV)构成.在爆磁压缩发生器运行以前,用5 min给储能电容器充上6 kV的电压.实验证明4 Ah的铅酸蓄电池可以通过高压逆变系统给220 μF的电容器充电超过五次以上,此时电池的电压仍然高于11 V.由此可见,以蓄电池加高压逆变器和储能电容器作为其初始能源,能够满足体积小、稳定提供较大的初始能量的能力.同时利用级联型爆磁压缩发生器,能够在较小的体积和重量的情况下驱动较大的电感负载(4 μH),实现输出电流120 kA,电流的上升时间为15 μs的预期目标.
Abstract
A compact helical explosively-driven magnetic flux compression generator (MFCG) using rechargeable battery as initial energy source has two stages, one acts as an energy amplifier, the other serves as a pulse sharper to match high inductance load. The initial energy source inciludes a capacitor of 220 μF charged with 6 kV,a rechargeable battery and a high voltage converter. It takes about 5 minutes to charge the battey with 6 kV before the MFCG running, and the voltage of the bettery is still larger than 11 V after five times. The results shows that this compact initial energy source system can stably offer larger initial energy, and the cascaded MFCG which is small and light can offer 120 kA current with a risetime of 15 μs to a large inductance load which is 4 μH.
