                         DC/DC converters with power density equivalent to state-of-art 
                         technology in Brazil and these converter, when built with 
                         optpocouplers, are able to operate for the whole lifetime of a 
                         space mission. The converter is designed to meet the requirements 
                         of payloads in missions like CBERS (China Brazil Earth Resources 
                         Satellites) e PMM (Multimission Platform). The built prototype and 
                         observations of its electrical and thermal behavior are presented. 
                         The effects of space radiation, thermal excursion and the limit of 
                         degradation of the optocouler Current Transfer Ratio is 
                         analyzed.",
