Power conditioning and distribution unit of China-Brazil satellite CBERS3

Brazil has participated, over the years, in the development of remote sensing satellites, for imaging purposes, known as CBERS (China-Brazil earth resource satellite). With a polar orbit of 778 km of altitude, it takes around one hundred minutes to complete a revolution around the Earth, with an eclipse of about half an hour, resulting from the passage of the satellite through the Earth´s shadow. Designed for a 3 years mission period, its power conditioning and distribution unit shall be able to provide, with high reliability, 1820W of continuous power to the spacecraft in a harsh environment of radiation-induced damaged on electronic components, large temperature variations in orbit and extreme vibrations during launch phase.
