    • 由於在寬輸入與寬輸出的範圍下，不對稱半橋轉換器的功率開關有柔性零電壓切換的優點，因此適用於高頻高輸入電壓的功率應用。選擇替代的半波整流器，並針對不對稱半橋半波整流轉換器在第二章做詳細的介紹。此外，不對稱半橋轉換器的輸入電流不連續且輸入電流漣波大，進一步影響電磁干擾以及限制功率密度的性能。
    近年來，已經有提出降低漣波的文獻。藉由電路內置輸入電流濾波器來降低輸入電流漣波。因此，選擇降低輸入電流漣波轉換器與半波整流器結合，在第三章做詳細的介紹。再者，兩個轉換器皆使用相同的規格，如下所示：輸入電壓300V至400V，輸出電壓24V，輸出電流1A至10A，並詳細分析與測試電路，以證明其可行性。

    Asymmetrical half-bridge converter (AHB) features ZVS operating under wide line and load ranges so that it is suitable for high frequency and high input voltage power conversion applications. An alternative half-wave rectifier is introduced instead and an asymmetrical half-bridge converter with half-wave rectifier (AHB-HWR) is proposed in this thesis. However, the AHB has pulsating input current waveform, that associated to the EMI problem.
    There are several ripple reduction converters have been proposed in the literatures. The built-in input filter is obtained by using current ripple cancellation mechanism. To employ this mechanism, therefore, an input current ripple reduction asymmetrical half-bridge converter with half-wave rectifier (RRAHB-HWR) is proposed. Furthermore, two proposed converters with same specifications 300V-400V input and 24V/10A output are analyzed implemented and tested to demonstrate their feasibilities.
