    Abstract: 本論文設計實現一台具有自我控制調整輸出能力的平行直流供電系統。在直流電源供應單元(Power Supply Unit, PSU)模組化上,本論文結合並聯背板來將六台直流電源供應單元架構為一個整合式的直流電源供應模組。在直流供電效率的改善上,本論文採用圖形化程式語言LabVIEW以及控制平台NI-USB 8451來控制這個整合式的直流電源供應模組。此方式可以縮短開發、資料收集及測試驗證的時間,更能以視覺化程式語言來幫助除錯。由實驗結果可知,本論文所提的模糊控制方法確實能夠配合伺服器系統的電力需求來有效的調節電源供應器的數量,進而提升效率來達到節能的效果。雖然每台電源供應器所能節省的電力不多,但在長時間使用很多電源供應單元的情況下,本論文所提的方法將能夠節省不少的不必要的電力浪費。此外,本論文所提的電源配置方式與控制方法亦可以提供給資料中心與雲端伺服器做為設計與規劃電源產品之參考。
    An automatic self-adjustable of parallel DC supply system is proposed. In this thesis, the modular DC power supply unit (PSU) integrated six PSU with power distribution board to become integrated DC power supply system. For efficiency improvement of the DC supply system, the graphical programming language LabVIEW and the interface I2C device NI-USB 8451 are used to control the automatic self-adjustable of six-parallel DC PSU system. The time of the development, data collection from each power supply, and verification will be reduced by the proposed method. Moreover, the visual programming language can be easily used to debug. Some experimental results are presented to illustrate that the proposed fuzzy control method can adjust the quantity of PSU based on the tactual power requirement of the server system. The power saving of each PSU even though not much, but the proposed method can save a lot of unnecessary waste of electricity in the case of long-term use of a large number of PSU. Moreover, the proposed power supply configuration and control method can also provide the data center and the cloud server as a reference for the design and planning of power supply products.
