Abstract
Aiming at the characteristics of small size and energy shortage for standard CubeSat architecture such as Aoxiang-Sat,topology for a novel centralized and modular electric power system for nanosatellite was proposed,which used the design of multiple independent solar energy conversion units with maximum power point tracking to increase efficiency of solar energy utilization. With the idea of using Commercial off the shelf devices in the power system,the design method ensuring software and hardware reliability for each major unit of the system was explained,the work process,status monitoring and protection mode of the system were further discussed to make the system have better antifault capability and operation autonomy. The validity of the designed system and the good engineering application value were verified through the ground experiments and on-orbit data analysis of Aoxiang-Sat.
