本文將發展一單相/三相電能轉換系統，該單相/三相電能轉換系統由一三相四線式電能轉換器、一零序變壓器組及一濾波電容器組成。本文所發展之單相/三相電能轉換系統應用於單相配電系統作為三相主動電力調節器，單相/三相電能轉換器是採用電流控制式控制三相四線式電能轉換器產生兩個電流成份，分別為零序電流成份及正序電流成份，正序電流成份用以建立高品質三相輸出電壓供應三相負載，零序電流成份則經零序變壓器流向單相配電系統，在單相配電系統端輸入一與單相市電電壓同相位之弦波電流。由於本文所發展之單相/三相電能轉換系統只包含一級電能轉換器，所以具有電力架構及控制電路簡單之優點，本論文並將建立一硬體雛形以驗證本文所發展之單相/三相電能轉換器之功能。

In this thesis, a single-phase/three-phase power conversion system is developed. The single-phase/three-phase power conversion system is configured by a three-phase four-wire power converter, a zero-sequence transformer set and a filter capacitor. The single-phase/three-phase power conversion system is applied to the single-phase distribution power system to perform a three-phase power conditioner. The current-mode control is applied to control the three-phase four-wire power converter so as to generate a positive-sequence current and a zero-sequence current. The positive-sequence current is used to generate the high-quality three-phase voltage suppling to the load. The zero-sequency current is passed to the single-phase distribution power system through the zero-sequency transformer such that the input current of single-phase/three-phase power conversion system is sinusoidal and in phase with the voltage of single-phase distribution power system. Since the proposed single-phase/three-phase power conversion system is configured by only one power converter, it has the advantages of simplifying the power circuit and control circuit. For verifing the performance of the proposed single-phase/three-phase power conversion system, a DSP-based hardware prototype is established and test.
