Abstract

Computer simulation results of the flux compression generator (FCG) loaded with an inductor has been presented in this paper. Simulation research has been performed in order to select the parameters of FCG load coil properly. The influence of the load inductance and resistance on the current gain factor and the magnetic field energy accumulated in a load coil has been investigated.

Highlights

  • Formation of the high current surges with a very short rise time in the inductive load is necessary for the implementation of many scientific and technical research [2]

  • At the moment when the value of the current from the primary source reaches the maximum value, the explosion of material located inside the wiring system is initiated, while the input terminals are shorted by crowbar

  • The change of the flux compression generator (FCG) inductance Lg occurs during the detonation process of the explosive located in the armature as a result of the shorting process of the individual turns of the coil

Summary

Introduction

Formation of the high current surges (in the order of MA) with a very short rise time (in the order of μs) in the inductive load (induction coil) is necessary for the implementation of many scientific and technical research [2]. This type of current surge has been usually formed in Flux Compression Generators (FCG) [1, 2, 3]. The electromagnetic field, the enormous density of this energy reaches the desired effect [1]
