Abstract

Abstract: A compact explosively driven ferromagnetic generator for explosive magnetic flux compression generators was developed. Its working principle and process are analyzed by establishing a magnetoelectric transformation model. The static magnetic field of open magnet in the electrical source is analytically calculated and numerically simulated. The calculation method of magnetic flux of magnet section is presented, and a design method of pulse source is provided. The pulse sources of different magnet materials and detonation method are test. The results show that the N35 explosively driven ferromagnetic electrical source (double-ended detonation) outputs 1 100 A pulse current at 1.2 μH inductive load; higher output current and energy parameters in the load could be obtained by using high-performance magnet material; the energy conversion efficiencies of single-ended detonation and double-ended detonation are η_t≮14.6% and η_t≮24.4%, respectively; the explosively driven ferromagnetic generator is only suitable for driving a lower impedance load, and the indirect feed mode is more reasonable when it is used for HMFCG' initial energy source.Key
