本論文針對電動車的能源電池，設計成一個簡單、便利及高效率的複合式電池系統。採用分散式電源系統的觀念，以多電源模組並聯的方式來提供能量給負載使用。在升壓型轉換器的設計上，引入K因數(K factor)作為計算回授補償器的依據。電源供應器採多組並聯使用，可以提供電子設備高可靠度及大電流輸出的電源供應需求。但並聯電源供應器必須藉由均流控制技術，才能確保負載電流均勻地分配至每一個模組上。本文採用應用最廣泛的主僕均流技術，主要是由外迴路控制法以及直接主僕均流匯流排所組成，除具較佳的故障容許能力，且容易實現模組化的設計等優點。由實驗結果可知電路能量轉換效率為90%以上，且其均流控制在負載變動期間亦能將負載電流平均分配。The purpose of this thesis is to design a simple, convenient and efficient hybrid battery system for electric vehicle. Using the structure of distributed power systems, the energy is supplied by the parallel multi-power modules. The design of feedback compensations network for boost converter design is based on the K factor algorithm. Paralleled use of multi-power supply can provide electronic equipments with power demand of high reliability and high current output. However, paralleled DC-DC converters system requires current-sharing techniques to ensure that the load current can be equally distributed to everyone converter. The applications of master-slave current-sharing control are most widely used. The master-slave current-sharing control is used in this paper, which is mainly composed of outer-loop control and direct master-slave current-sharing bus, and it has the advantages of good fault tolerance and easily to realize module design. From experimental result, the circuit of energy conversion efficiency is above 90%, and current sharing control during changes in load can also be excellence.
