本論文設計並研製具耦合電感之高升壓轉換器。轉換器使用單一開關結合串接型升壓轉換器、耦合電感及切換電容以達到高升壓的目的。下半級為串接型升壓轉換器，上半級為耦合電感與切換電容電路，疊接式可減少開關應力，並有傳統升壓型轉換器之開關電壓箝位的功能，高轉換比使責任週期操作於適當範圍。
文中先後對模式分析、穩態分析及元件參數設計進行討論。最後，製作輸入電壓24 V，輸出電壓400 V，輸出滿載功率為400 W高升壓直流轉換器之雛型，並以實驗結果證實所提轉換器之可行性。

In this thesis, a novel non-isolated high step-up converter is implemented. The converter is a cascade boost converter with a coupled inductor and switching capacitor to obtain high conversion ratio. The lower part is cascade boost converter. The upper part is the coupled inductor and switch-capacitor.
The operating mode, steady-state analysis, and component parameter designs are discussed in this thesis. Then, a prototype circuit with 24V input voltage, 400 V output voltage and output power of 400 W is implemented to verify the feasibility of the proposed converter.
