摘要

本論文係提出一由傳統前向式轉換器所衍生之高升壓轉換器，並採用主動式箝位電路來回收漏感能量以降低功率開關元件上之應力。相較於傳統前向式轉換器，本論文所提出之衍生型電力轉換器其特色為利用第三去磁線圈結合電荷幫浦及增加第四耦合線圈，實際上僅只增加一個元件，即可使電壓轉換比大幅提升。於本論文中，將詳細敘述所提架構之基本操作原理與理論推導，並搭配模擬與實作結果來驗證所提架構之可行性與有效性。除此之外，本論文採用Altera公司所生產之現場可程式邏輯閘陣列晶片EP1C3T100C8N來作為系統控制的運算核心。

A high step-up converter, derived from the traditional forward converter, is presented herein, which uses an active clamping circuit to recycle the energy stored in the leakage inductance so as to reduce the voltage stress on the power switch. As compared with the traditional forward converter, the proposed converter, without the active clamping circuit considered, actually uses only one additional component so as to make the voltage conversion ratio improved greatly. In the thesis, the basis operating principles and mathematical deductions of the proposed converter are described in detail, and sequentially some simulated and experimental results are provided to verify the feasibility and effectiveness of such a converter. In addition, the filed-programmable gate array (FPGA), named EP1C3T100C8N made by Altera Co., is used as a system control kernel.
