電池充電管理為基礎的零電壓切換全橋轉換器

本文研究了一種以移相全橋變換器為基礎的電池管理系統(BMS)的充電策略。電池的充電方法採用恆定電流和恆定電壓充電模式（CC-CV）。本電池管理系統可立即監控電池充電狀態，並適時調整轉換器柵極信號的相移，以保持輸出電流恆定在CC模式，及保持輸出電壓恆定在CV模式，期間轉換器開關可保持在零電壓開關（ZVS），以達到最佳的效率。在這項研究中，採用了控制器UC3875作為全橋相移轉換器在零電壓切換和充電模式控制。最後，實作一部1 kW移相全橋轉換器以驗證所提出的充電技術，對於一組48V鉛酸電池以恆定電流15A充電時，最好的效率可以達到88％。

This thesis studies a charging strategy using phase-shifted full-bridge converter based battery management system (BMS). Battery charging method adopts a constant current and constant voltage charging mode (CC-CV). The battery management system can always monitor the state of charge of the battery immediately, and adjust the phase shift of the gate signal of the converter to maintain a constant output current in the CC mode, and to keep the output voltage constant in CV mode, while the converter can be kept at zero voltage switch (ZVS) to achieve the best efficiency. In this study, a controller UC3875 is employed for the full-bridge phase-shift converter to make gate switching at zero voltage and realize charging mode control. Finally, a 1 kW phase full-bridge converter is implemented to verify the proposed charging strategy; when a set of 48V lead-acid battery with a constant current of 15A charging, the best efficiency can reach 88%.
