摘要: | 本文提出單相並聯式主動濾波器於三相四線配電系統,改善三相四線配電系統中性線過載問題。單相並聯式主動濾波器可以安裝靠近每一相的非線性二極體整流器負載,補償二極體整流器負載所產生的諧波電流。此外本文採用空白時間補償的脈波寬度調變技術,可以改善單相並聯式主動濾波器的輸出電壓精度。本文所提出之方法經由模擬與實驗驗證可以改善三相四線配電系統中性線過載問題。 This study presents single-phase shunt active filter for three-phase four-wire distribution systems to alleviate the overloading of the neutral conductor.
