Abstract:	本論文提出一基於混合結構之切換式電容的雙向高轉換比交錯式轉換器。有鑑於現有的交錯式轉換器在高電壓且高電流應用中的缺點，本論文透過切換式電容電路架構的改進，來改善此類轉換器的特性，在電壓轉換比、元件電壓應力與轉換器效率之間取得平衡，避免高電路阻抗及漣波，同時具備限制元件電壓應力的功能。此外，本論文使用MOSFET替換二極體，使轉換器能夠雙向傳輸功率。本論文進行了詳盡的計算分析，使所提出轉換器架構之各項參數與規格可透過公式計算得知，以增加應用時之便利性。最後，模擬和實際製作電路來驗證本電路架構確實可行且具其效果，為高階數、高電壓且高電流之交錯式轉換器應用提供更優良的解決方案。 ;This thesis proposes a bidirectional high conversion ratio interleaved converter based on a hybrid structure of switched–capacitor. In view of the weaknesses of the existing interleaved converters in high-voltage and high-current applications, this thesis improves the characteristics of converters through the improvement of the switched–capacitor circuit structure. Achieve a balance between voltage conversion ratio, component voltage stress, and converter efficiency, to avoid high circuit impedance and ripple, and have the function of limiting components voltage stress. In addition, this thesis uses MOSFET to replace diodes, enabling the converter to transmit power in both directions. This thesis has carried out detailed calculation and analysis, so that the various parameters and specifications of the proposed converter structure can be calculated through formulas to increase the convenience of application. Finally, simulation and experimentation of circuits to verify that the circuit structure is indeed feasible and effective, providing a better solution for high–stages, high–voltage and high–current applications of interleaved converter.
