鉛酸蓄電池在應用上相當廣泛，如汽、機車電力系統、電源供應器和不斷電系統等，然而當電能使用完後必須對蓄電池進行充電。所以本論文研製一雙向降-升壓式轉換器來針對高電壓120V與低電壓12V之蓄電池補充電能。
本文中雙向降-升壓式轉換器具有構造簡單、重量輕、體積小、成本價格低等優點。並可以運用在其他轉換器上，如升壓式轉換器、降壓式轉換器、返馳式轉換器等。在文章中說明電路操作特性原理與電路模式加以分析，另外在電路設計方面先使用工程軟體IsSpice模擬分析來完成轉換器之電路模擬波形，再由模擬所得之參考數據來完成實體電路與實測之顯示結果。
最後完成新型雙向降-升壓式轉換器，並量測相關波形再配合模擬進行模式驗證之正確性，證實此電路能夠達到硬式切換的特性及85%以上之效率。

Lead-acid batteries widely used in various applications, such as automotive power system, telecom power supply uninterruptible power system, and so on. However, charge the battery after the electric energy finished is used. The main aim of this thesis is to 120V high-voltage battery and a low voltage 12V supplemental power. Accordingly, a novel bidirectional Buck-Boost converter is proposed in this thesis.
In the proposed a novel bidirectional Buck-Boost converter bears the advantages such as simpler circuit structures, lighter weight, smaller volume, as well as lower cost. In addition, can be used to the other converters, like boost converter, buck converter and the flyback converter…ect. The article includes the experimental results of control analysis, constitution of circuit. Also in circuit design, complete the circuit simulate wave with the IsSpice, then to complete the measured results with the circuit combination reference data.
Finally, accomplish a novel bidirectional Buck-Boost converter according to the operating of the converter, the parameters of the calculation with the computer and circuit implementation, confirmed that this circuit can achieve a hard and fast switching characteristics and high conversion efficiency of more than 85%.
