Abstract

Classically, electrolytic capacitors have been used for dc filter applications. However, the inherent advantages of 'electrolytics' such as self-healing and high energy density make them an attractive candidate for pulse circuitry. To this end, a new type of electrolytic capacitor has been developed specifically for high peak current applications. Preliminary results of an ongoing research effort to determine the operational characteristics of this new type of electrolytic are reported. Electrical characteristics such as equivalent series inductance (ESL) and equivalent series resistance (ESR) has been determined for the first generation test units. Along with the ESR determination, the adiabatic temperature rise per pulse was measured to assist in cooling system design as well as operation in environments where heat rejection is limited. The new electrolytic capacitors may facilitate the development of a new class of pulse generators based on high energy density components. Pulse generators for mass launchers, very low impedance loads, and space-based applications where volume and weight density are at a premium are ideal target applications for pulse electrolytics. High power flashlamp drivers for rod and slab lasers are of particular interest. With recent advances in fast solid state switching such as the dynistor, together the ultrahigh energy density capacitors can result in very compact pulsers. Compared to other energy storage alternatives, the electrolytic capacitor still offers the best source of Joules per dollar for traditional applications.
