The characteristics of traditional power control structure and the improved one are compared. The control methods of them are described briefly. The design process of buck con-verter parameters and control strategy between the DC bus and load in the satellite power system is studied. A parameters calcu-lating method is given. The correctness of the method was verified with Matlab simulation software.
