摘要:三相四線制APF 中,采用電容中點式拓撲,直流側電容上要流過很大的電流,對直流側支撐電容的耐流能力要求很高。本文以一臺30kVA 的三相四線制電容中點式APF 為例,通過對比分析,證明了在電容中點式APF 中,選擇薄膜電容比電解電容要更適合。

Abstract:In the split-capacitor of three-phase four-wire APF, current flows through the DC_link capacitor, so demand the DC_linkcapacitor high current capacity. In this paper, a 30kVA three-phase four-wire capacitor APF, for example, by comparing the analysis toprove that film capacitors to be more suitable than electrolytic capacitors.
