Magnetic flux compression generator with output 70 kJ and pulse duration 20 μs

A two-stage helical explosive magnetic flux compression generator (type 08 MFCG) is described in this paper. The generator design parameters were obtained from calculation by computation code BCYSSYS for HEMG pulsed-power source based on equivalent circuit. Experimental results show that, type 08 MFCG can output pulse current up to 220 kA and energy up to 72 kJ on 3 μH inductance load within the effective pulse duration of 21 μs, and the experimental results are compared with the calculated ones, which demonstrates the feasibility of the code BCYSSYS for generator design.
