本論文提出ㄧ採用疊接技術之高昇壓型轉換器，電路採用傳統昇降壓型轉換器疊接而成，藉此架構可使切換開關於適當之責任週期下得到高昇壓轉換比。而本轉換器之單開關疊接昇壓技術，亦有架構簡易等優點，可延伸至其他昇壓型轉換器作應用整合，以獲得更高電壓增益。文中針對所提出之高昇壓型轉換器電路架構，探討其動作原理及分析電路特性。最後，研製一輸入電壓為24 V，輸出電壓200 V，輸出功率100 W之疊接式昇降壓型轉換器雛型電路，以實驗與模擬結果驗證本論文理論分析之可行性。

In this thesis, a novel high step-up cascode boost converter is proposed. The circuits topology of the proposed converter is composed of two conventional buck-boost converters with cascode connect such that a high step-up voltage gain with a proper duty ratio can be obtained. Besides, the cascode concept also can be adopted to construct other step-up converters. The operating principle, steady-state analysis, and efficiency analysis are presented. Finally, an experimental prototype with 24 V input and 200 V/ 100 W output is implemented to demonstrate the theoretical analysis.
