Design and Verification of Chang’e 5 Probe Power Supply and Distribution System

The function of the power supply and distribution system and the multi cabin combined power supply scheme are introduced in this article in consideration of the main mission characteristics of Chang’e 5 probe. Through energy balance analysis as well as multi bus syncretic control and other key technologies, the design problem of multi task, multi mode, high reliability, light and small power supply and distribution system for the probe in a complex space environment is solved. On orbit flight results show that the power supply and distribution system functions normally and reliably with a good performance. The proposed analysis and design methods of Chang’e 5 power supply and distribution system can fulfill and ensure the reliable realization of robotic sample return mission on lunar surface, and provide reference for the design of power supply and distribution system in future lunar exploration projects and other deep space exploration fields.
