Energy Storage Capacitors of High Energy Density

The capacitor requirements of modern EMP generators are such that conventional energy storage capacitors are not satisfactory. New concepts of capacitor design will make available high energy density units with reliable performance for future needs. A review of state-of-the-art energy storage capacitor characteristics is presented, delineating the effect of dominant operational mode on the physical shape and energy density of a number of capacitor types. A specialized configuration of energy storage capacitor, tailored to the requirements of EMP generators, is described and its performance characteristics detailed. These new capacitor concepts may be applied to specific applications in fusion research under certain circuit conditions which are discussed.
