本論文提出一具耦合電感倍流整流之半橋雙LLC轉換器研製。本轉換器利用雙諧振槽與倍流整流電路達到有效降低元件電流應力、提高轉換器效率、增加降壓轉換比、分散變壓器體積之優點。本論文首先進行電路動作模式分析及等效模型之推導,並比較輸出倍流整流電路使用電感及耦合電感之差異。最後實作一輸入直流電壓為400V,輸出為24V/21A之雙諧振槽半橋LLC諧振轉換器,其電路最高效率可達93.4%,滿載效率可達91.6%,以驗證理論之可行性。
In this thesis, a half-bridge dual LLC converter with coupled-inductor current doubler rectification is proposed. The advantages of the proposed converter are that the dual resonant tanks and current doubler rectifier can reduce the current stress of components, achieve high efficiency, increase step-down conversion ratio and high power density. The operating principle and steady-state analysis are addressed. The characteristic differences between current doubler rectifier using inductor and coupled-inductor are also presented. To verify the analysis, a laboratory prototype dual LLC resonant converter with input voltage of 400V and output 24V/21A is implemented. The maximum efficiency of proposed converter is 93.4%, and the full-load efficiency of proposed converter is 91.6%.
