摘要

本論文提出一新型單相三開關交流/交流轉換器，其電路架構是由三個功率開關、三個電容器、一個升壓電感器及一個輸出電感器所構成。該轉換器應用廣義零向量控制策略，將整流器與換流器整合為單一級轉換器，並具有輸入單位功因、輸出入弦波電流、能量再生並降低成本的優點。本論文使用TMS320F2812全數位化數位訊號處理器與VisSim軟體來設計及實現，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，提出部分實驗結果來驗證新型轉換器之可行性。

In this thesis, a novel single-phase three-switch AC/AC converter is proposed. The proposed converter consists of three power switches, three capacitors and two inductors. Based on the generalized zero vector (GZV) control strategy, the proposed converter has several advantages such as single stage control, input unity power factor, sinusoidal input/output current, energy regeneration, and low cost etc.. Besides, a fully digital control TMS320F2812 digital signal processor (DSP) and VisSim simulation program are adopted to implement the control circuit. Finally, some experimental results are presented to verify the feasibility of the proposed converter.
