摘要
本文提出了一种适用刀片式结构超级计算机的优化供电方式,将刀片式结构超级计算机供电广泛采用的两级直流母线、三级电源变换的供电方式改为一级直流母线和两级电源变换,同时仍保留了可接入后援蓄电池的直流电输入接口。文中对在超级计算机上实现这种优化供电方式的主要技术难点进行了论述,并提供了详细的解决方案。这种优化的供电方式已经在某超级计算机系统中得到了实际应用。应用效果证明,这种供电方式能够提高供电效率,降低电源成本,减少电源器件对插件板板面的占用,提高电源系统的可靠性。对在电源系统设计工作中如何降低超级计算机能耗的其他方法也做了简要介绍。
An optimized power supply architecture for blade type supercomputers is proposed in this paper. Instead of the two-level DC bus, a three-stage conversion architecture is commonly used in blade type supercomputers,which uses a one-level DC bus, two-stage conversion architecture, and retains the DC interface to the backup batteries. The difficulties for implementing the proposed architecture are discussed in this paper and the solutions are provided in detail. The proposed architecture has been implemented in a supercomputer system. The real-life performance has proved that, compared to the other existing architectures, the proposed architecture im- proves the power efficiency, reduces the component cost and the space required on the plug-boards, and improves the overall reliability of the power supply system. Other possible methods of reducing supercomputer power consumptions are also discussed in this paper.
