Development of compact explosively driven ferromagnetic seed source for helical magnetic flux compression generator

Development of compact explosively driven ferromagnetic seed source for helical magnetic flux compression generator

A compact explosively driven ferromagnetic generator (FMG) is developed for seed power source of helical magnetic flux compression generator (HMFCG). The mechanism of FMG is studied by establishing a magnetoelectric conversion model. Analytical calculations and numerical simulations are conducted on...
