Electric power supplies for spacecraft are reviewed. Primary spacecraft power sources, comprising solar cells and arrays and electric batteries, and the operating principles and fabrication technology of photovoltaic solar cells and arrays and storage batteries, including the nickel-cadmium cell, are discussed and manufacturing processes are illustrated. The design of power regulation and control circuits in solar- and battery-powered spacecraft is considered and possible designs of switching regulators in spacecraft electronic power conversion circuits are presented. Past and current work at TRW on spacecraft solar arrays, battery systems, power subsystem engineering and power processing and conversion is outlined. Future spacecraft power systems are expected to be largely influenced by the Space Shuttle environment, and improvements in the efficiency of solar arrays, nickel-cadmium and nickel-hydrogen batteries, and power control electronics are foreseen.
