零電壓轉移升壓式蓄電池充電器

由於傳統的硬式切換功率開關元件並非為理想，因此功率開關元件在截止與導通時，會產生電壓突波與電流突波、提高開關切換損失，造成效率降低、元件應力增加及容易損壞。相較於傳統的升壓式轉換器，本論文利用柔性切換技術研製零電壓轉移升壓式蓄電池充電器於共振時進行開關切換能更有效降低開關之切換損失、提升充電效率及降低電磁干擾。針對兩個主動開關的切換，依據開關導通與截止的情形分析電路工作原理，並藉由等效電路及電路操作方程式以設計共振時的最佳電路參數。實測結果驗證所提充電器電路的理論正確性，充電器的平均充電效率高達88.2%。

Since traditional hard-switching power switch components have non-ideal characteristics, a voltage surge or current surge generated under conduction and cutoff, the power switch components reduces the efficiency, increases the component stress and facilitates breakage. This work employs soft-switching technology to realize a novel battery charger with a zero-voltage-transition (ZVT) boost converter which increases the charging efficiency above, reduces the switching losses below, and reduces the electromagnetic interference (EMI) below, those of battery chargers with conventional boost converters. The optimal circuit parameters are set based on circuit analyses under the conduction and cut-off conditions of two active switches using equivalent circuits and the circuit operation equations. Experimental results demonstrate the theoretical effectiveness of the proposed battery charger. The practical mean charging efficiency of the developed battery charger is as high as 88.2%.
