本論文主要提出一具高升壓比之耦合電感升壓型轉換器。文中採用耦合電感的操作方法，應用在高升壓比的場合。本文所提轉換器採用兩組耦合電感來改變電感儲能的方式，進而改變輸入電流的上升斜率。由於本論文電路架構的改變，使得電路的轉移函數不同於傳統升壓型轉換器，因而具備高升壓比之特性，且電路架構並不複雜。
最後，設計並實現輸出功率200 W、輸入電壓15 V、輸出電壓400 V之具高升壓比之耦合電感升壓型轉換器，並透過模擬軟體Simplis進行電路模擬，加以驗證電路的正確性與可行性。由實驗結果得知，最高效率可達93.43%。

This thesis presents a novel high voltage-gain boost converter with coupled-inductor. The discussed converter adopts a coupled-inductor circuit for high step-up voltage ratio application. The proposed converter applies two coupled inductors to change the way that inductors store energy, thereby changing the rising slope of the input current. In this thesis, due to the change of the circuit structure, the transfer function of the circuit is different from the conventional boost converter. The proposed circuit has the characteristic of high step-up voltage ratio and the circuit architecture is not complicated.
Finally, a 200-W high voltage gain boost converter with coupled- inductor is designed and implemented, through simulation to verify the correctness and feasibility of the circuit. The input voltage is 15 V, and the output voltage is 400 V, and the highest efficiency achieves 93.9%.
