European Space Agency (ESA) has addressed the key points like higher power demand and system efficiency, system reusability, adaptability and flexibility, decrease in system mass, size and cost, increase in modularity and standardization for the next generation (NG) power systems on future missions at 8th Space Power Conference. Since the purpose of a power distribution module is to ensure reliable delivery of electrical power and prevent failure propagation, under all foreseeable conditions, during all mission phases, reliability and redundancy become critical issues in design. This paper describes UYGAR, which is the power distribution module designed in TUBITAK UZAY for Low Earth Orbit (LEO), Geostationary Earth Orbit (GEO) and Science Missions with its single point failure free, 100 kRad radiation tolerant and internally redundant electronic design while considering the key points addressed by ESA and the experiences gained in TUBITAK UZAY's previous satellite missions RASAT and GÖKTÜRK-2. This paper describes the high reliable, radiation tolerant, flexible, and unique design details compatible with ECSS-E-ST-20C and AIAA-S-122-2007 of NG power distribution module, UYGAR, which is considered as a part of higher power demanded and more complex power system architecture for next generation missions of various orbits. Moreover, the qualifications test results and details are presented.
