Equivalent circuit computation for cascaded helical flux compression generator

A cascaded helical explosively-driven magnetic flux compression generator (HMFCG) has more than one stage and the follow stage captures the magnetic flux of the preceding one and further amplifies the energy. In this paper, the inductance and resistance computation uses the image current model and the magnetic flux coupling between the two stages takes the capture model. At the same time the equivalent magnetic flux loss resistance is supposed to be directly proportional to the equivalent direct current resistance. The computed results of dynamic-cascaded HMFCG fit the experiment data to some extend. This equivalent circuit model is simple and practical, which can be used to optimize the HMFCG parameters and applications. Additionally, the capture model has some reference values to computi
