Abstract:	由於系統架構簡單、低成本和可擴充性，並聯三相主動前端轉換器的使用變得廣泛。然而，並聯三相主動前端轉換器的脈波寬度調變會造成環路電流。環路電流主要受脈波寬度調變週期中的零序向量影響。本研究提出用於並聯三相主動前端轉換器之多載波脈波寬度調變器。多載波脈波寬度調變器可以合成期望的輸出電壓而不使用零序向量。因此，使用多載波脈波寬度調變器可以抑制並聯三相主動前端轉換器的環路電流。此外，多載波脈波寬度調變器也可以減少三相主動前端轉換器的共模電壓。本研究所提用於並聯三相主動前端轉換器之多載波脈波寬度調變器的性能，經由模 The use of parallel three-phase active front-end converters has become more popular due to simplicity, low cost and expandability. However, the pulse width modulation (PWM) switching of parallel three-phase active front-end converters causes circulating c
