Compact, Repetitive Pulsed Power Driver Design for Emerging High Power Radio Frequency Sources

on October 11, 2013

The goal of this Phase I research is to demonstrate a scaleable pulse power modulator circuit with a resistive load that meets scalable voltage, current, and peak power requirements for a 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.
