Description
Power generation through heat to electrical energy conversion for space applications faces distinct challenges not encountered in terrestrial settings, where Rankine and Brayton cycles have traditionally been predominant. The unique environment of space necessitates the adoption of either static converters, leveraging solid-state physics, or closed-cycle dynamic converters. While thermoelectric generators have historically been the primary choice for heat-to-electrical energy conversion in space applications, their relatively low efficiencies and limited scope for enhancement pose significant challenges as the power demands of space missions increase. This necessitates the exploration of alternative power generation methodologies to meet the evolving requirements. This thesis provides a comprehensive analysis of various power conversion technologies for space applications, focusing on the comparative study of static and dynamic converters, with a particular emphasis on Stirling converters. Other power systems discussed include thermoelectric, thermophotovoltaic, thermionic, and Brayton converters. Through comparative analysis, the research identifies the most promising converters for future space applications.
