    A robust, accurate, broadband, AC sensor using fiber optics that is being developed for space applications at power frequencies as high as 20 kHz is described. It can also be used in low- and high-voltage 60-Hz terrestrial power systems and in 400-Hz aircraft systems. It is intrinsically immune to electromagnetic interference (EMI) and has the added benefit of excellent isolation. The sensor uses ... View full abstract»

    The state-of-the-art of electric vehicles (EVs) is discussed with examples of prototype vehicles-Electric G-Van, Chrysler TEVan, Eaton DSEP, and Ford/GE ETX-II. The acceleration, top speed, and range of these electric vehicles are delineated to demonstrate their performance capabilities, which are comparable with conventional internal combustion engine (ICE) vehicles. The prospects for the commerc... View full abstract»

    It is noted that the projected increase in satellites needed to satisfy future military, scientific, and commercial missions will soon be overwhelming current ground-operations capabilities. An intelligent processing architecture, IntelliSTAR, that addresses the potential of automating the entire satellite operations domain (planning, scheduling, execution, and analysis) is discussed. The architec... View full abstract»

    A high-voltage opening switch that uses gate-turnoff thyristors (GTOs) in series and successfully operates at voltages higher than the rated voltage of the individual devices has been demonstrated. The switch design and construction are described, and experimental results are given. The demonstration system is rated at 5 kV and uses 1-kV devices. A larger 24-kV system is under design and will use ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (385 KB)

    The basics of performing the initial electrical power subsystem (EPS) sizing for a spacecraft using solar cells for an energy source and batteries for energy storage are covered. The basic engineering inputs are described. The outputs are the first estimate of the number of solar cells, the solar array area, and the number of batteries required. A spreadsheet program to keep track of the inputs, p... View full abstract»
