An Armature-Stator Contact Resistance Model for Explosively Driven Helical Magnetic Flux Compression Generators

Abstract

Although helical magnetic flux compression generators (HFCGs) have been in use for more than four decades, no one has been able to satisfactorily model their behavior. To bring computed currents into agreement with experimental values, tuning factors or anomalous flux loss factors are used. Such factors are not universal, and they must be adjusted for each generator design, or for different operational parameters (e.g., seed current or load inductance) for a given design. Many HFCG modeling codes have been reported over the years with various types of these empirical factors.
