本論文旨在提出快速能量轉換的機制能快速雙向，以雙向直流至直流轉換器為電路架構，主要應用於直流匯流排與電池側之間的能量傳遞。首先文中將分別討論充電模式與放電模式之動作原理，接著，對轉態模式作進一步的分析，透過電路之操作模式找出能量續流的路徑，最後以數位信號處理器為控制平台，搭配數位控制擬定控制策略，完成能量之快速轉換。
此轉換器具有高轉換比且架構簡單的優點，接著，文中將進一步介紹穩態分析及元件參數設計，最後，研製一滿載500 W，連接24 V電池及200 V直流匯流排之雙向直流至直流轉換器，透過實驗結果來驗證能量快速轉換之可行性，當轉換器操作在DCM或BCM模式時，能量皆可在一個切換週期內完成轉換，另外，當轉換器操作在CCM這種能量較大的模式時，必須先將能量續流後再進行轉換。

In this thesis, a technique for rapid energy conversion is proposed, thereby converting the energy effectively. A bidirectional DC-DC converter is used as the circuit architecture, which is mainly applied to the energy conversion between the DC bus and the battery side. Above all, the thesis will discuss the operating principles of the charging mode and the discharging mode, respectively. Then, the transferring state will be further analyzed, and the path of energy freewheeling is found through the operating mode of the converter. Finally, the digital signal processor is used as the control platform, and the digital control is used to formulate a control strategy to complete the rapid energy conversion.
This converter has the advantages of high conversion ratio and simple architecture, then, the steady-state analysis and component parameter design are further introduced. Finally, a prototype converter with for 24 V battery, DC bus of 200 V and output power of 500 W is implemented to confirm the feasibility of rapid energy conversion. When the converter is operated in DCM or BCM, it can complete the energy conversion in one switching cycle, on the other hand, when the converter is operated in CCM, the energy must be freewheeled before conversion.
