This paper proposes a satellite power system based on H-bridge energy router which can connect multiple sources and loads with various voltage ranges. The solar arrays, batteries and dc loads can be integrated or isolated from the power system via router individually without affecting each other. The energy router is basedon multi-port High Frequency Transformer(HFT) and phase shift is applied to control power or voltage of each port. A 4 ports simulation model is built by MATLAB/Simulink, the results show the system is robust in both sunlight and eclipse periods.
