本論文所提架構是將升降壓轉換器結合耦合電感與靴帶電容而成的一個新型升壓轉換器。相較於傳統的升壓轉換器,本論文所提之電路擁有更高的電壓轉換比,其輸出的電壓轉換比還可以利用圈數比的觀念來改變其升壓比,增加其設計的彈性。除此之外,此電路可依據電壓轉換比及瓦數的需求,分成單開關元件或雙開關元件來使用,且其為非浮動開關,使其在驅動部分的線路相對地簡單,故實用性高。於本論文中,將詳細敘述所提架構之基本操作原理、相關數學推導與理論分析,並搭配模擬與實作結果來驗證所提架構之可行性及有效性。

In this thesis, a novel high step-up converter is presented, which combines the buck-boost converter, the coupling inductor and the bootstrap capacitor. By doing so, the proposed converter possesses a high voltage conversion ratio, which can be obtained based on not only the duty cycle but also the turns ratio so as to increase design feasibility. Furthermore, such a converter can be used with a single switch or double switch according to the requirements for the voltage conversion ratio and the power. Above all, the used switch is driven without isolation and hence the gate driving circuit is relatively simple, thereby upgrading the industrical application capability of this converter. In this thesis, the basic operating principles and the associated mathematical deductions are firstly described in detail, and finally some simulated and experimental results are provided to demonstrate the feasibility and effectiveness of the proposed high step-up converter.
