本論文主要為提出一種改良型之非隔離型直流對直流升壓轉換器。升壓轉換器無論是在再生能源發電或儲能裝置上均有廣泛應用。本文所提出的改良電路分為兩級並透過三個絕緣閘雙極電晶體 (Insulated Gate Bipolar Transistor, IGBT)開關來做控制,第一級電路架構為一改良型的輸入電流互補電路,透過兩個反相操作的開關以及並聯的電感來將輸入端的電流漣波有效抑制至最小,此一作法不僅可使輸入端穩定更可降低單一電感所需承載的高電流壓力, 且透過本文所提出的可自由調變之多脈波PWM控制方式,可使輸入端電流漣波在任意開關導通週期內皆維持最小。
第二級電路架構使用切換式電感取代單一電感以增加輸出電壓增益比,實作電路為一輸入電壓40~60 V,輸出電壓150~400 V,輸出功率300 W之昇壓轉換器,並藉實驗結果與比較驗證本論文架構。

The thesis presents an improved non-isolated boost DC-DC converter. The boost DC-DC converter has been widely applied on renewable generation and energy storage. Improved circuit proposed in this thesis is divided into two stages through three IGBT switches to perform the control. The first stage is a modified circuit architecture of the input current ripple complementary boost converter. The current ripple through two switches can be effectively reduced by inversely operating. This approach not only enables a more stable input source but also reduces the high current carrying stress of single inductor. Through the proposed single-sided multiple pulse width modulation control the input current ripple can be maintained in a minimum range at any duty ratio.
The second stage apply switched-inductors replaced for a single inductor to increase the voltage gain ratio. Finally, a boost converter with an input voltage of 40~60 V, an output voltage of 150~400 V, and output power of 300 W is implemented. The experimental results are verified with theoretical analysis of the proposed structure.
