    • 近年來，由於能源短缺，再生能源漸漸被重視，其中燃料電池和太陽能電池被視為有發展潛力的能源，然而兩者所產生的輸出電壓低且變化範圍大，所以無法直接提供一般電器使用。 因此，需要一級高昇壓轉換器將低電壓提升至穩定的高壓(200V or 380V)輸出。傳統的Boost轉換器，卻有電壓增益的限制及需要較大的責任週期(Duty cycle)的問題。為了克服此問題，本論文提出新式非隔型升壓電源轉換器，藉由堆疊Three-State Switching Cell Boost轉換器以及雙繞組倍壓整流電路等技術達成高升壓輸出的需求。所提出之電路，除了有高轉換比、連續電流、寬輸入電壓範圍及低開關電壓應力外，其中雙繞組倍壓整流電路的輸出電壓漣波消除能力優於傳統的倍壓整流電路。所以，小電容值的非電解電容可以被使用，且整流二極體的零電流切換可以被達成。最後，實作電路與理論相互驗證。

    Stacking a two-winding voltage doubler rectifier on top of a three-state switching cell boost derived converter, a non-isolated high step-up converter is proposed. In addition to having high conversion ratio, non-pulsating input current, wide input range operation, low output voltage-ripple, and low voltage stress on switch and diode, the proposed converter has additional output voltage-ripple reduction advantage over the conventional voltage doubler rectifier. As a result, smaller non-electrolytic output capacitors can be used and thus zero-current switching of rectifier diode can be achieved. Besides, the operational principle and circuit analysis, several prototypes with 100 kHz, 36-75V, 380V/380W output are implemented and tested to demonstrate their feasibility.
