本論文提出一個新型三相六個開關交流/交流轉換器，其電路架構是由六個功率開關、三個電容、三個輸入側電感及三個輸出側電感所組成。該轉換器應用正弦脈波寬度調變技術及零向量控制策略，將整流器與換流器整合為單級式轉換器，並具有輸入單位功因、輸出入弦波電流、降低成本等優點。此電路控制策略是藉由規劃開關責任週期之操作區間，使整流器與換流器操作在同一週期內。其中，利用固定電容比例將整流器與換流器的責任週期規劃在最佳區域，使該轉換器工作更加穩定。本論文使用VisSim軟體與TMS320F2812全數位化數位訊號處理器來設計與實現，並應用狀態空間平均技巧建立此新型轉換器之數學模型。最後，提出部分實驗結果驗證新型轉換器之可行性。

In this thesis, a novel three-phase AC/AC converter is proposed. The proposed converter consists of six power switches, three capacitors, three input inductors and three output inductors. The proposed converter has several advantages such as sinusoidal input-output current, adjustable frequency, unity input power factor and lower switch cost etc.. Based on the sinusoidal pulse width modulation techniques and zero vector control strategy, the converter combines three-phase AC/DC converter and three-phase DC/AC inverter to generate a single-stage converter controlled in the same period. By fixed capacitor ratio, the duty functions of converter and inverter are operated in optimum period for more stable control. The software VisSim and TI TMS320F2812 are adopted to implement the proposed converter. Besides, the mathematic model of the proposed converter is established by the state average technique. Finally, some experimental results are compared with the proposed theory for verification.
