Cascaded helical magnetic flux compression generator with a battery as initial source

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 includes a capacitor of 220μF charged with 6kV,a rechargeable battery and a high voltage converter. It takes about 5 minutes to charge the battery with 6 kV before the MFCG running, and the voltage of the battery 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.
