本論文旨在研究與研製鋰電池放電器,並以數位信號處理器實現數位控制。本論文選用的架構為主動箝位電流饋入式全橋直流-直流轉換器,並採用兩組並聯的方式實現,開關以錯相式方法控制,如此可以解決大電流的問題、降低輸入/輸出電流漣波及提升功率密度。二次側採用倍壓整流電路,使變壓器匝比減半,提升整體轉換效率。數位控制器協調控制電能轉換器模組間的開關閘極信號操作,包含錯相信號、電路保護、軟啟動等功能。另外設計輔助電源提供兩組輸出:Vcc1 (15 V/1.5 A)提供給驅動電路IC及電壓/電流感測器、Vcc2 (5 V/1 A)提供給數位信號處理器及保護功能電路。最後本論文設計、研製與測試一台3 kW鋰電池放電器,實驗結果驗證此系統的可行性,轉換效率亦可達90 %以上。
This thesis presents the study and implementation of a 3-kW discharger for Li-ion battery with digital control by using a Texas Instruments DSP chip. In order to carry out this research, a parallel interleaved active-clamp current-fed full-bridge DC-DC converter is proposed. The gate driving signals of the two converters are interleaved to solve the high current problem, reduce the current ripple and improve the power density. Furthermore, the turns of the transformer can be reduced by half by the voltage-doubler circuit at secondary side. A digital controller is in charge of coordinating the gate driving signals, including the interleaved operations, circuit protection, and soft start function, among various power converter modules. An auxiliary power supply is designed to provide two output voltages. Vcc1 (15 V/1.5 A) is supplied to driver IC and voltage/current sensors. Vcc2 (5 V/1 A) is supplied to the DSP digital controller and protection circuitry. Finally, a 3-kW discharger for Li-ion battery is designed, implemented and tested. Experimental results are shown to verify the feasibility of the developed system. A high conversion efficiency over 90 % can be achieved.
