本文提出一種以三組單週期控制的單相交流-直流轉換器結合全橋式直流-直流轉換器實現三相交流-直流轉換之研究,輸入側為三組單相交流-直流轉換器做Y型連接,其後接三組全橋相移轉換器且在輸出側做並聯連接,以完成三相交流-直流轉換。所提系統具有功率因數校正功能,且透過單周期控制方式與傳統型控制方法相比更為輕便;傳統型控制方法需要偵測市電電壓,在較高壓輸入時感測元件設計相較為複雜,本文採用的修正式單週期控制,可減少電路元件及簡化控制電路之設計。本研究並探討輸入側三組交流/直流轉換器均壓的控制方法,以及輸出側全橋式直流/直流轉換器並聯均流控制的方法,最後以實作三組共1500W系統來驗證所提出的架構可行。
This thesis presents a study of three-phase AC-DC conversion using three sets of single-cycle controlled based single-phase AC-DC converters, and each output is cascaded by a full-bridge DC-DC converter. The proposed input side includes three sets of single-phase AC-DC converters with Y-type connection, and their output are following with three sets of full-bridge phase-shift converters in parallel connection on the output side to complete the three-phase AC-DC conversion. The proposed AC-DC converter adopts single-cycle control based method to implement the power factor correction function. This method is easy and convenient than the traditional control method. The traditional method needs to detect the mains voltage, and the design of the sensing element is relatively complex when the input voltage is relatively high. The presented single-cycle control adopted in this This study discusses the input voltage control method for the three AC/DC converters on the input side, and the current sharing control method for full-bridge DC/DC converters in the output side. Finally, three sets of total 1500W systems are used to verify the proposed idea is feasible.
