    Abstract: 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。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,正序電流成分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 paper, 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 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.
