本論文主要研究一具有倍流整流器之半橋串聯諧振轉換器在大電流輸出之應用。本論文提出之SRC半橋串聯諧振倍流式轉換器具有高效率及低漣波電流的優點。本電路架構使用之諧振電感分別在變壓器一次側及二次側,二次側之諧振電感具有降低輸出電流漣波。二次側之中心抽頭式整流器結合了耦合電感後,具有降低電流應力之功能。本電路架構具有中央抽頭整流式與倍流整流式兩者之特點。本研究中實現一台輸入380V~400V及輸出12V之300瓦電源轉換器做為測試,並使用軟體SIMetrix-SIMPLIS做為電路模擬工具,透過此電路模擬及實作結果來探討此電路之可行性。
This thesis aims to study a half-bridge series resonant converter with current doubler rectifier for high current output applications. The proposed series resonant converter has the advantages such as high efficiency and low current ripple. Two resonant inductors are used in the resonant tank at the primary and secondary sides, respectively. The resonant inductor in the secondary side can effectively reduce the output current ripple. A coupled inductor is combined with the current doubler rectifier to reduce the current stresses for secondary rectifier. The proposed topology has the benefit of both the central tap rectifier and current doubler rectifier. In this study, a 300W laboratory prototype for the proposed half-bridge series resonant converter with current doubler rectifier is realized and tested for 380V~400V input voltage and 12V output voltage. The simulation and experimental results are shown to verify the feasibility of the proposed scheme.
