摘要

本論文係提出三種新型的高升壓型轉換器架構。架構一為，改良KY升壓型轉換器的新型高升壓型轉換器，相較於KY升壓型轉換器，此架構乃藉由耦合電感的觀念以彌補KY升壓型轉換器之電壓轉換比不足的缺點，同時耦合電感之漏感的能量可以被回收。架構二、三為改良基於電荷幫浦電容之雙升壓電感轉換器的新型高升壓型轉換器。相較於基於電荷幫浦電容之雙升壓電感轉換器，架構二為，於原本的電路中額外加入一個倍壓電路及一組線圈，以提升電壓轉換比，並將三組線圈繞製於同一磁性元件上，如此一來將可減少整體電路的體積。除此之外，耦合電感之漏感能量皆能回收。架構三為，改善架構二之元件過多的缺點，藉由將架構二之耦合電感的第三組線圈串接於電荷幫浦電容上，來移除所使用的倍壓電路，進而降低元件的數目，同時也可以達到與架構二相同的電壓轉換比。再者，電荷幫浦電容於儲能時所造成的電流突波也可以被第三線圈所抑制，並且此耦合電感之漏感能量皆能回收。於本論文中，首先針對所提之新型高升壓型轉換器進行動作原理說明與分析，緊接著將藉由模擬以驗證所提電路之可行性，最後再藉由Altera公司所生產之現場邏輯閘陣列晶片EP1C3T100C8N來做為系統控制的運算核心，實際驗證所提電路之有效性。

There are three types of voltage-boosting converters to be presented herein. Type 1 is derived from the KY boost converter along with the coupled inductor, and is used to improve the voltage conversion ratio of the KY boost converter. At the same time, the energy stored in the leakage inductance of the coupled inductor can be recycled. Regarding types 2 and 3, they are derived from the converter with two voltage-boosting inductors and one charge-pump capacitor. As compared with the converter with two voltage-boosting inductors and one charge-pump capacitor, type 2 has one additional voltage doubler and one additional winding so as to enhance the voltage conversion ratio, and has three windings coupled together so as to reduce the size. In addition, the energy stored in the leakage inductance of the coupled inductor can also be recycled. As compared with type 2, type 3 has the third winding of the coupled inductor connected in series with the charge-pump capacitor and removes the voltage doubler, so as to reduce the number of components. It is noted that type 3 has the same voltage conversion ratio as type 2 has. Moreover, the surge current in the charge-pump capacitor can be inhibited by the third winding and the energy stored in the leakage inductance of the coupled inductor can also be recycled. In this thesis, the basic operating principles and mathematical deductions for the proposed three types of voltage-boosting converters are firstly given, and eventually some simulated and experimental results are provided to demonstrate the feasibility and effectiveness of the proposed converters. By the way, a field-programmable gate array, named EP1C3T100C8N made by Altera Co., is adopted as a control kernel.
