Compact, Repetitive Pulsed Power Driver Design for Emerging High Power Radio Frequency Sources Navy SBIR FY2013.2 Sol No.: Navy SBIR FY2013.2 Topic No.: N132-129 Topic Title: Compact, Repetitive Pulsed Power Driver Design for Emerging High Power Radio Frequency Sources Proposal No.: N132-129-0534 Firm: UES, Inc. 4401 Dayton-Xenia Road Dayton, Ohio 45432 Contact: Rabi Bhattacharya Phone: (937) 426-6900 Web Site: www.ues.com Abstract: The goal of this Phase I research is to demonstrate a scaleable pulse power modulator circuit with a resistive load, meeting scaleable voltage, current and peak power requirements for high power radio frequency (HPRF) source. Gallium Arsenide (GaAs) based high gain Photoconductive Semiconductor Switches (PCSS) will be used for this demonstration. The Phase I demonstration will be limited to 10-100 Hz for a few seconds at varying pulse widths. Based on the results of Phase I demonstration, design and modeling of key elements for compact, repetitive, pulsed power driver to meet Navy's requirements will be pursued in Phase II. Benefits: A high voltage, solid state, compact, repetitive pulsed power driver optimized for emerging high power radio frequency sources (HPRF) will be developed in this project. These HPRF sources have the potential to enable solutions for applications of interest to the U.S. Navy such as small vessel mounted and man-portable directed energy weapons. Potential commercial applications include a variety of communications, sensor and medical applications requiring compact, high power RF systems. Return
