摘要
介绍了7.5 k W三电平APFC的研制过程。对三电平APFC进行了建模分析,论述了主要工作原理,对空间矢量控制算法进行了仿真验证。采用电压外环和电流内环双闭环控制,给出了实验过程中PI参数的调节步骤。实验结果验证了理论分析的正确性。
The development process of 7. 5 kW three-level APFC is introduced. The modeling of three-level APFC is analyzed, and the main working principles is presented and verified by simulation based on space vector control algorithm. Dual closed loop control is adopted with voltage outer loop and current inner loop. The adjustment steps of PI regulating parameters of three-level APFC are given in experiment process too. The experimental results verify the validity of the theoretical analysis.
