P.O. Box 71 Hanover, New Hampshire 03755 Contact: Calman Gold Phone: (603) 643-3800 Web Site: www.creare.com Abstract: Industrial medium-voltage capacitor charging converters are currently limited in applicability for future Electromagnetic Rail Gun (EMRG) systems by low-power density, undesirable charging profiles, and incompatibility with shipboard DC voltages, liquid cooling, EMI, shock, and vibration requirements. A need exists to provide improved medium-voltage, power dense, and modular electronics to meet the electrical, environmental, and mission requirements of future combatant EMRG systems. In Phase I, we propose to design an innovative high-energy and power-dense modular capacitor charging topology for pulsed power systems. We will demonstrate feasibility by engineering analysis and simulation, and demonstrate a sub-scale working prototype. In Phase II, we will optimize the design for electrical performance, reliability, mechanical packaging, and compatibility with shipboard system installation requirements as a prerequisite to building and testing a full-scale prototype. Benefits: Commercial pulsed-power systems benefiting from improved capacitor charging systems include water and food sterilization processes, metal forming and laser machining equipment, and linear accelerators used for both high energy physics research and medical radiation therapy. Additional benefits of this technology will enhance high-energy capacitor charging systems in fusion energy research and alternative energy storage systems. Return
