基於金鷹演算法之三階混合全橋LLC諧振轉換器效率最佳化

為了解決Adjustable voltage r的問題，作者何昆哲 這樣論述：

現今環保意識抬頭，電動車逐漸成為趨勢，用於車用電池充電器等應用場合之功率轉換器需具備大輸出功率、寬輸出電壓以及高功率密度等特點。因此本論文實作一台三階混合全橋LLC諧振轉換器以符合上述應用需求。本論文首先提出一固定工作頻率，調節輔助開關責任週期之控制法，降低控制難度，使電路能工作於二階模式與三階模式，並根據輸出電壓與負載情況進行平滑切換，實現寬輸出電壓與高效率之目標。此外，由於目前文獻中提出之效率最佳化研究皆僅考慮單一負載情境，而轉換器應用於電池充電應用場合時，其負載會隨充電過程而持續改變，針對此一需求，本論文提出一結合LLC諧振轉換器之工作區域分析、損耗分析及金鷹演算法之效率最佳化設計方法

以求解最佳諧振槽設計參數，進而實現最佳綜合效率。本研究最後實際完成一台1250W，輸入電壓500V，輸出電壓360-500V，最大輸出電流2.5A的三階混合全橋LLC諧振轉換器，針對120串ICR-18650M之電池組規格，驗證本研究所提出的控制法與金鷹演算法求得之最佳諧振槽參數的正確性與可行性。由實驗結果可知當輸出電壓500V且輸出80%負載時，所提電路可達最高效率97.3%，且針對實際定電流-定電壓充電法各負載之時間比重進行量測可得綜合效率為95.7%。
