高效的电源系统已被开发出来，以实现数据中心中的环保服务器机器。减少了交直流转换的级数，提高了电源单元在低负载时的供电效率，提高了电源效率。为了进一步完善这些方法，本文介绍了内置机架式UPS方法、PSU动态运行次数控制方法和电源辅助方法。在保持UPS功能的前提下，供电效率提高了13%以上。此外，在电源单元数量较少的情况下，还实现了电池供电时负载快速上升的功能。
Highly effective power supply system has been developed to achieve eco-conscious server machines in data center. The number of conversion steps between AC and DC are decreased and power supply efficiency of PSU at low load is improved to increase the power supply efficiency. To develop these approaches, the built-in rack UPS method, dynamic operation number control method of PSU, and power assistance method are described in this paper. The power supply efficiency was improved 13% or more by implementing the proposed method keeping the function of UPS. In addition, a function was achieved to withstand a rapid load rising by the battery's power supply in the condition of small number of operating PSU.
