摘要(中)

由於汽車上同時存在12 V與48 V系統，因此本文設計可調節功率之雙向直流/直流轉換器，其主要功能為調度車內12 V系統與48 V系統間的能量流動。藉由此轉換器之設計，實現電能可以根據不同情況執行雙向傳輸來滿足兩側系統所需功率，並提高能源的轉換效率。
本文的硬體架構主要為多相同步整流雙向轉換電路，採用Linear公司所生產之型號 LTC3871控制晶片，可執行電路軟啟動、電壓電流動態調節及電路保護機制等功能。此晶片可執行高達12相(多IC)之連動操作，且能鎖相之頻率高達460 kHz，既能操作在高頻以減少被動元件之體積，亦能多相同步整流操作以減少單一線路流通之電流，使此電路架構能在高功率情況下進行雙向電能傳輸。
最後，本文使用電路模擬軟體Psim驗證系統架構且實際製作一部操作於高頻之多相同步整流雙向轉換器，並藉由實測結果來驗證此架構之可行性。

摘要(英)

Since there are both 12 V and 48 V electric system in the vehicle, a bidirectional DC/DC converter is designed in this paper . It proposes on control the energy flow between the 12 V and 48 V electric system. With this design of converter, the electrical energy can be bi-directionally flow to supplement the power required by the electrical system and improve the energy efficiency.
The electric circuit of this paper is multi-phase synchronous rectification bidirectional converter circuit. The circuit uses a model LTC3871 control chip produced by Linear Company. It can perform soft start, dynamic regulation of voltage and current and circuit protection mechanisms. This chip can realize multi-phase operation up to 12-phase (multi-ICs), and the phase-lockable frequency up to 460 kHz. Therefore, the circuit can operate at high frequency to reduce the volume of passive components, and also can operate at multi-phase synchronous rectification to reduce the current flow on single phase. It makes the circuit can realize bidirectional energy transmission under high power conditions.
Finally, this paper uses the circuit simulation software Psim to verify system architecture and produces a multi-phase synchronous rectification bidirectional converter. It confirms the feasibility of this architecture by the results.
