The explosively-pumped magnetic flux compression generator (FCG) is a pulsed-power current amplifier powered by an explosion. This thesis surveys FCGs, demonstrating their general operation; develops a new magnetic-field-strength-based model for FCGs in the form of a generalized cylinder that more accurately captures losses to magnetic diffusion than commonly employed circuit models, but maintains simplicity in the form of a low order DAE; develops a simplified means of calculating the inductance of FCGs, providing a bridge between the field-based and circuit models; presents a design of a full loop FCG system (a topology underserved by existing literature) and an experimental setup to verify the designed loop generator; and proposes a class of non-explosive magnetic flux compression generators. The designs and models herein provide new tools and jumping-off points for further research into FCGs, particularly in the miniaturized systems gaining popularity and in the potential for reusable flux compression power sources.
