Design of distributed DC power supply system for unmanned ground vehicle computer system

This paper designs a distributed DC power supply system for unmanned ground vehicle computer system, Using N+a distributed power supply design. Each power board is designed with digital acquisition, power adjustment and digital control functions. The power boards communicate with each other through the power communication bus. The power board with minimum position serial number collects the working state of all power boards in the power supply system, and controls the output power of each power board according to the working state of the power supply system. Finally, each power board can be in the best working state, effectively improving the power supply capability and the working reliability of the power supply system.
