    Abstract: 本文提出一「新型雙向直流至直流轉換器」,此轉換器具
    有高電壓轉換比,可作為電池側與直流匯流排之間雙向傳遞能
    量。當轉換器操作於放電模式時,輸入電源為電池,藉由對兩
    獨立電感並聯充電、串聯放電升壓至直流匯流排;當操作於充
    電模式時,輸入電源為直流匯流排,藉由對兩獨立電感串聯充
    電、並聯放電降壓至低壓電池側。本文中首先介紹數種雙向轉
    換器架構,接著分析本文所提轉換器之動作原理與穩態特性。
    最後,實作一低壓側24 V、高壓側200 V、放電模式功率500
    W、充電模式功率264 W 之雛型電路,以驗證本轉換器之性
    能。經由實驗可知,放電模式滿載效率為85.5%;充電模式滿
    載效率為89.0%。
    In this paper, a novel bidirectional DC-DC converter is proposed. The proposed bidirectional converter with high voltage ratio is used to transfer energy between battery and DC bus. When the converter is operated in the discharging mode, two inductors are charged in parallel and are discharged in series. It can step up battery voltage to DC bus voltage. When it is operated in the charging mode, two inductors are charged in series and are discharged in parallel. It can step down DC bus voltage to battery voltage. This paper first briefly introduces several bidirectional converters. Following that operating principles and steady-state characteristics of this converter will be analyzed. Finally, a laboratory prototype with battery voltage 24 V, DC bus voltage 200 V, discharging mode power 500 W, and charging mode power 264 W is implemented to verify the performance. The full load efficiency of discharging mode is 85.5%, and the full load efficiency of charging mode is 89.0%.
