摘要

对于高性能计算系统来说，功率传输变得尤为重要。本文实现了一种新型的垂直功率传输（VPD）架构，该架构具有较高的传输效率和系统计算性能。一个12-1.83 V电压调节器（VR）板通过盲/埋孔工艺构建。基于VR板与主板的兼容设计，该VR板直接与服务器主板组装形成计算系统。静态输出和瞬态响应试验表明，VPD样机具有良好的稳定性。样机的峰值和满载效率分别为93.0%和91.5%，优于横向功率传递（LPD）和之前的报道。这种VPD设计还可以直接向中央处理器供电。因此，我们进一步研究了系统的计算性能，以评估构建的VPD在真实服务器环境中的应用，得到VPD系统的基准得分为15 538，高于LPD服务器（14 599）。通过路径电阻（Rpath）仿真可以看出，该方法的优越性能可归因于减小了配电网的电阻。最后，我们将VR板的制造工艺延伸到主板，方便了电源转换器在服务器主板背面的直接组装。构建的VPD实现了可扩展的效率。

A Vertical Power Delivery Architecture for High-Performance Computing

Power delivery is becoming especially critical for high-performance computing system. This article realizes a novel vertical power delivery (VPD) architecture with high delivery efficiency and system computing performance. A 12–1.83 V voltage regulator (VR) board is built via blind/buried via process. Based on compatible design of VR board and mainboard, this VR board has been directly assembled with a server mainboard to form a computing system. Static output and transient response tests indicate superior stability of VPD prototype. Peak and full load efficiencies of prototype are confirmed to be 93.0% and 91.5%, respectively, better than lateral power delivery (LPD) and previous reports. This VPD design also enables direct power supply to central processing unit. Therefore, system computing performances have been further investigated to evaluate application of built VPD in real server environment, and benchmark score of VPD system is acquired to be 15 538, higher than LPD server (14 599). The superior performances can be attributed to reduced power distribution network resistance, revealed by path resistance (R_path) simulation. At last, we have extended the manufacture process of VR board into mainboard, facilitating direct assembly of power converter on back side of server mainboard. The built VPD realizes scalable efficiencies.

期刊介绍： The IEEE Transactions on Power Electronics journal covers all issues of widespread or generic interest to engineers who work in the field of power electronics. The Journal editors will enforce standards and a review policy equivalent to the IEEE Transactions, and only papers of high technical quality will be accepted. Papers which treat new and novel device, circuit or system issues which are of generic interest to power electronics engineers are published. Papers which are not within the scope of this Journal will be forwarded to the appropriate IEEE Journal or Transactions editors. Examples of papers which would be more appropriately published in other Journals or Transactions include: 1) Papers describing semiconductor or electron device physics. These papers would be more appropriate for the IEEE Transactions on Electron Devices. 2) Papers describing applications in specific areas: e.g., industry, instrumentation, utility power systems, aerospace, industrial electronics, etc. These papers would be more appropriate for the Transactions of the Society which is concerned with these applications. 3) Papers describing magnetic materials and magnetic device physics. These papers would be more appropriate for the IEEE Transactions on Magnetics. 4) Papers on machine theory. These papers would be more appropriate for the IEEE Transactions on Power Systems. While original papers of significant technical content will comprise the major portion of the Journal, tutorial papers and papers of historical value are also reviewed for publication.
