摘要

隨著雲端服務快速發展與資訊服務需求與日俱增，為能確保資料中心關鍵設備與裝置的安全、穩定可靠運行，機房工程基礎架構中的備援(Redundant)電力系統愈趨重要。
本論文以開發自動電源轉換器(ATS)之硬體電路設計為主要研究，並做為提供軟體介面平台使用；以業界機型進行改良及降低成本，增加安全機制並探討自動電源轉換器在機櫃上的應用與節能之關係。研究重要成果如下：
1、業界ATS皆為單機設計，本論文自主開發設計為雙機型式，並進行模組化、集成設計，降低成本、增加硬體安全設計提升競爭力；設計符合TIA- 942-2005 Tier II 等級以上要求，提高設施可用性、穩定性和安全性。
2、業界產品安裝為固定式鎖附於機箱上，本論文採熱插拔(Hotswapable)的模組化設計。各模組皆可從機殼的正面抽出，維修時不需停機，大幅度降低了維修時間與成本，增加機房管理人員作業安全性。
3、機櫃需具有不斷電和高可靠度，採用快速轉換開關模組，降低零組件故障而導致系統當機的或然率；業界設計採用SSR轉換開關模組成本高,本論文採用SCR轉換開關模組設計降低成本兼具高可靠度，本論文並以平均故障間隔(MTBF)進行實例分析。
本研究結果可提供其他企業或學術單位進行相關技術開發與應用參考。

As the Cloud service evolved rapidly and the service demand of information technology increases quickly, the redundant power system within the data center infrastructure is more important than ever for ensuring the critical equipment’s stability and safety.
This paper studies the hardware circuitry design of the automatic transfer switch (ATS) developed by a particular company, and then utilizes such design on a software platform. This study takes the design, which is already used in the industry, to do further improvement on cost and safety mechanism, and then discusses its relationship with the server rack’s energy-saving and application. The major findings are as the following:

1、The current ATS designs within the industry are all based on a single machine unit. This paper develops a dual-machine design and implements module integrated concept, cost down, and additional hardware safety for competivity. This design adheres to the requirement of TIA-942-2005 Tier II level, which ensures its applicability, stability, and safety.
2、The installation of the products within the current industry is to physically fix it onto a server machine unit. This paper develops a hot-swapable module for machine front-end installation while still keeping the power on, which lowers the maintenance time and cost and enhances operators’ safety.
3、Server rack must not be powered off and must have high reliability, and so it should use a fast-speed transfer switch module with low component failure rate. The current industry utilizes the high-cost solid state relay (SSR) design, while this paper utilizes the silicon controlled rectifier (SCR) design for lower cost and high reliability. The comparison is based on mean time between failure (MTBF)

The findings of this paper can be a referenced for further academic study and enterprise’s application development.
