Abstract:

To meet the power supply requirement of highperformance computer system, 12V DC bus distributed power system is adopted in this paper, and the power supply schemes of computing cabinet and motherboard are described. The power supply for processor in computing motherboard is analyzed in detail, and the parameters of loop gain, compensation network and output filter are presented. The application results show that this power supply can fully meet the requirement of highperformance computer system.

Key words: highperformance computer;distributed power system;motherboard;processor;power supply
