The Design and Verify of Multi-Module Spacecraft Joint Power Supply System

The power supply system of muti-module spacecraft in domestic and foreign is investigated, and the power supply characteristics and typical power supply solutions of muti-module spacecraft is analyzed in this paper. Taking a deep space lunar probe as an example, a design scheme of combined power supply between multiple module is presented in this paper.The simulation model is established, and the different working modes of the combined power supply are simulated and verified. The comparison between the experimental data and the simulation results verifies the feasibility of the design. As the same time, this paper also provides an important theoretical basis for further improving the design capability of multi-module spacecraft power system and developing a more reliable spacecraft power supply system. It can be used to guide the design of multi-module spacecraft power system in the future.
