Abstract:

(School of Computer Science,National University of Defense Technology,Changsha 410073,China)Abstract:The paper designs and implements the soft startup for the circuit board with 12V power supply of the Tianhe highperformance computer system. Using the latest control technique, we design the hot swap circuit with large current, and carry out corresponding tests. This technique has been applied on designing all kinds of PCBs in the Tianhe computer system.
