Abstract:

Intellectualized power distribution technology for aerospace field is developing rapidly. Distribution system is an important part of the spacecraft electrical system, whose performance is directly related to the success or failure of the mission, in order to improve the reliability and flexibility of the distribution system, the paper proposed a design of intellectualized power distribution system based on FPGA and SSPC. The paper first introduced the development situation of the spacecraft intellectualized power distribution technology, specifically elaborated design ideas of overall program and key techniques, and also analyzed the advantages :flexible control, troubleshooting and system reconstruction, high reliability, low system weight, which were brought by using FPGA, SSPC, bus communication. The system experimentation has been completed, and the results show that this system is steady and reliable, it has comprehensive application foreground. 
