The overall objective of this Phase I effort is to investigate two topologies for generating >500kV pulses in an ultra-compact geometry that can be scaled over a wide range of sizes ranging from a geometry that would fit in a 2.75 inch rocket to that of a GMLRS warhead that could be seven inches in diameter, and 2ft. long. The proposed work will provide a new state of the art power supply topology suitable for driving a wide range of DEW systems suitable for use in munitions. The modular design of the Radiance proposed system has application to radar systems, as well as High Power Laser (HPL) systems, both of which are of interest to the Department of Defense (DOD). The proposed design has several advantages over traditional pulse power drivers and will be capable of producing the requisite 500kV output with various seed source inputs
