Title: Novel, high-energy-density electrical-storage device for electric weapons. Final report 26 Feb-25 Aug 92

Abstract

Three different energy storage variants were developed and tested during Phase 1. Each was based on the close-coupled, thermopile storage principle. First, direct current was stored in a thermopile ring, which was open-switched into a dummy load to measure the energy release. In the second variant, alternating magnetic energy was stored in a split ring. Energy storage was caused by pumping alternating current in the thermopile circuit, connected as an LC oscillator. Both methods were found to store energy and each delivered pulse power, resulting in a twenty-to-one pulse-power advantage between energy released from the store and energy available from the power supply at the input. Power was drawn from these systems in a millisecond, making use of a specially developed, sequentially opening switch that takes full advantage of the MOSFET's nanosecond hyper-operating speed, the intermediate switching speed of a silicon controlled rectifier (SCR), and a slower speed electro-mechanical switch. Further work with modifications of these two storage methods led then to the development of an inductor-to-inductor (L2) electromagnetic storage system. This new type storage device seems to out perform the first two methods by roughly two orders of magnitude in storage capacity. During flux pump experiments, the authors alsomore » found that the L(2) prototype system could be tuned to operate efficiently at certain particular frequencies depending on the value of capacitor chosen, placed across the two conductors, to tune in steps between 50 Hz and 50 MHz, possibly operating efficiently in the GHz range.« less
