Abstract

DC/DC power converters that are capable of operating at cryogenic temperatures are anticipated to play an important role in the power systems of future NASA deep space missions. Design of these converters to survive cryogenic temperatures will improve the power system performance, and reduce development and launch costs. At the NASA Glenn Research Center Low Temperature Electronics Laboratory, several commercial off-the-shelf DC/DC converter modules were evaluated for their low temperature performance. Various parameters were investigated as a function of temperature, in the range of 20/spl deg/C to -190/spl deg/C. Data pertaining to the efficiency and voltage regulation of the tested converters is presented and discussed.
