摘要:

单周期控制以其结构简单、系统可靠稳定、功率因数高而得到推广,文中分析现阶段典型的PFC电路存在的缺陷,阐述了单周期控制的优势和单周期单相PFC的工作原理,并建立了相应的仿真模型,给出了对比仿真结果。结果表明,单周期控制的Boost PFC功率因数更高,谐波失真小。

关键词: 功率因数, 单周期控制, 模型仿真

Abstract:

One cycle control (OCC) of electronic devices is widely used due to its simple structure,high power factor and system stability and reliability.This paper analyzes the typical stage PFC circuit defects,explains the advantages of one cycle control and single-cycle single phase PFC,and establishes a corresponding simulation model.A comparison of the simulation results show that one cycle control of the Boost PFC has a higher power factor and smaller harmonic distortion.

Key words: power factor;one cycle control;model simulation
