Photovoltaic power for Space Station Freedom
Author_Institution :
NASA Lewis Res. Center, Cleveland, OH, USA
Abstract :
The Space Station Freedom is described with special attention to its electric power system. The photovoltaic arrays, the battery energy storage system, and the power management and distribution system are discussed. The current design of Freedom´s power system and the system requirements, trade studies, and competing factors which lead to system selections are referenced. This will be the largest power system ever flown in space. This system represents the culmination of many developments that have improved system performance, reduced cost, and improved reliability. Key developments and their evolution into the current space station solar array design are briefly described. The features of the solar cell and the array, including the development, design, test, and fight hardware production status, are given
