Design and simulation of power system for small body probe

The electrical power system of regulated and direct energy transfer was proposed, which was based on the problems of the power system of small body probe in the special deep space environment. According to the orbit characteristics of small body probe, the effects of environment factors and different loads on the electrical power system were analyzed and designed. The design of the electrical power system of the small body probe was based on energy balance, considering the relation between illumination and power. Finally, the design is demonstrated by numerical simulations.
