Simulation Study of PFC Boost Converter Based on Predicted Average Current Control

摘要

Introduced to predict average current control PFC Boost converter structure, and analyzes its operating principle, the average current control strategies equation is given by derivation. And a model of predict average current control PFC Boost converter is gained using Matlab Simulink simulation software and SimPowerSystems toolbox. Simulation results show that the predicted average current control PFC Boost converter with control circuit is simple and reliable, high input power factor, anti-interference ability, current harmonic distortion, etc, and is forecast to average voltage control strategy for the active power factor correction provides a novel, simple and feasible control methods.
