摘要

本論文提出一具能量再生與可調功因之單相交流/三相交流轉換器，其電路架構是由一個電容器串接一組單相全橋式電路與三相全橋式電路所組成，輸入端有一個電感器，而輸出端則有三個電感器。此轉換器利用廣義零向量技巧與死帶控制整合成一單級單相交流/三相交流轉換器，且輸入端具有可調功因與弦波輸入電流及減少開關切換損失；輸出端具有可升降壓、可變頻率及能量再生等優點。另外，應用狀態空間平均技巧建立所提之轉換器開關驅動訊號的數學模型。並利用VisSim及TI開發之DSP TMS320F28335實現系統的數位化控制器，以完成輸入整流側之功因修正與輸出交流側之迴授電路控制。最後，提出部分實驗結果與本論文所提之理論相比較，以驗證其正確性。

In this thesis, a single-phase to three-phase AC/AC converter is proposed. The proposed converter, which consists of a single-phase full-bridge and three-phase full-bridge, has four inductors and a capacitor. The proposed converter has several advantages such as adjustable power factor, sinusoidal input current, step up/down output voltage, adjustable frequency, single stage control, energy regeneration, and reduce the switching loss etc.. Besides, the mathematical model of proposed converter is built by using the state space averaging technique, generalized zero vector, and dead-band control. VisSim simulation program and DSP TMX320F28335 are employed to achieve digital control for power factor correct and feedback control. Finally, some experimental results are compared with the proposed theory for verification.
