Multi-Megawatt Inverter/Converter Technology for Space Power Applications
Abstract
Large power conditioning mass reductions will be required to enable megawatt power systems envisioned by the Strategic Defense Initiative, the Air Force and NASA. Phase I of a proposed two phase interagency program has been completed to develop an 0.1 kg/kW DC/DC converter technology base for these future space applications. Three contractors, Hughes, General Electric (GE), and Maxwell were Phase I contractors in a competitive program to develop a megawatt lightweight DC/DC converter. Researchers at NASA Lewis Research Center and the University of Wisconsin also investigated technology in topology and control. All three contractors, as well as the University of Wisconsin, concluded at the end of the Phase I study, which included some critical laboratory work, that O.1-kg/kW megawatt DC/DC converters can be built. This is an order of megnitude lower specific weight than is presently available. A brief description of each of the concepts used to meet the ambitious goais of this program will be presented.
