    Abstract: 本文主要研製一台適用低壓輸入、高壓輸出系統之500W
    二次側諧振槽串聯諧振轉換器(Series Resonant Converter,
    SRC)。一般半橋式串聯諧振轉換器較適用於高壓輸入、低壓
    輸出系統,當應用在低壓輸入、高壓輸出系統時,負載反射至
    變壓器一次側之反射阻抗極小,當品質因數設計在較小值時,
    由於特性阻抗為反射阻抗與品質因數之乘積,所以特性阻抗將
    非常地小,導致諧振槽內之諧振元件不易設計。針對此問題,
    本論文提出一創新架構之串聯諧振轉換器,其諧振槽置於變壓
    器二次側,如此將可改善諧振元件不易設計之問題。除了分析
    電路動作原理之外,並提供實驗數據以驗證理論之正確性。
    This thesis focuses on the study and implementation of a
    500-W series resonant converter (SRC) with a secondary-side
    resonant tank. In general, a half-bridge SRC with primary-side
    resonant tank is adopted for the applications with high input
    voltages and low output voltages. When it is applied on the
    system with a low input voltage and high output voltage, the
    equivalent output load reflected from the secondary to the primary
    will be very small. If the quality factor is designed to be low, the
    characteristic impedance, which is equal to the gain of the quality
    factor and the reflected output load, will also be small. This
    causes difficulty in designing the resonant tank elements. In this
    thesis, a new topology is presented. The series resonant converter
    with secondary-side resonant tank can solve the design problem
    of resonant elements. The circuit operations are analyzed. The
    experimental results on the prototype converter verify the
    effectiveness of the presented scheme.
