Lightweight Line Pulser.
Abstract
This report describes the work performed under contract F30602-76-C-0207 to study, develop, and demonstrate the feasibility of a compact, lightweight, modular, pulse-forming network (PFN). The PFN evolved is composed of identical LC modules and an input module that is optimized for a pulse-plateau ripple that satisfies the goal of + or - 0.5 percent. The ripple remains within this limit as modules are added or removed from the PFN to change the pulsewidth in 2 microsec steps. This low-ripple response is achieved without incorporating mutual inductance into the design, therefore, easing the module tuning and assembly. Mutual inductance has been considered indispensible in PFN's, but it is a roadblock for modular construction. Its elimination as a design parameter is the key to realizing the modular PFN. All electrical design goals are satisfied and the size goal was achieved by a wide margin. The realized volume energy density of 0.1 joules/cu in. was the best achievable with off-the-shelf capacitors. The goal of 0.5 joules/cu in. is not compatible with present state-of-the-art components at these power levels. Included herein are results of the following studies undertaken to satisfy the original contract objectives: Theoretical analysis of distributed and lumped constant lines that can realize the PFN.
