Abstract :
Power system designed and on-orbit performance are studied in this paper. First, the construction and performance of the power system are introduced. Then working principle and design method of controller, solar array and Li-ion battery of TianTuo1(TT-1) satellite, which was designed by national university of defense technology, are introduced in this paper. The design and realization of Maximum Power Point Tracking (MPPT) are studied emphatically. At last, performance of power system are analyzed in detail based on on-orbit data, which shows that energy is enough, power is balance, the design is reasonable and the configure meets the need of TT-1.
