Primal space power system is one of the important subsystem of spacecraft and responsible for the spacecraft to provide a safe and reliable power supply. The design of primal power system of spacecraft shall be considerated for its working safely and stably. The de-signed power system topology which is based on the solar cell panels-battery-power control system, is depended on S4R (The Sequential Switching Shunt Series Regulator). The work operation mode of S4R power control unit is analyzed, designed and simulated by the Saber,the S4R system was analyzed and proved the supply/charge/shunt working state, the result indicates that S4R power regulate unit can sel-regulate the power export, little undulation, dynamic response and Real-time very well.
