三相功率因數校正技術研究

摘要：本文采用三相六開關Boost拓撲實現三相PFC，三相拓撲通過物理解耦，增加電路冗余。Saber仿真分析比較了滯環電流變頻控制和平均電流定頻控制，仿真結果證明兩種控制方法均能很好地實現功率因數校正功能。 敘詞：三相PFC 滯環電流 平均電流 Abstract：Three-phase six-switch topology is used to achieve three-phase power factor correction in this paperphysically decoupling three-phase topology can enhance circuit redundanceSaber simulation analyzes and compares hysteresis current variable frequency control and average current uniform frequency controlsimulation results prove these two methods can both realize PFC perfectly Keyword：Three-phase PFC hysteresis current average current
