Research and simulation of active power factor correction

The fundamental theory and control methods of Active Power Factor Correction (short for APFC) are introduced in this paper. It analyzes and studies the APFC based on the average current control single-phase Boost type APFC circuit. In addition, the simulation model is built on the MATLAB and the results are shown in this paper. The results show the average current control single-phase Boost type APFC circuit, complete can achieve rectifier, high input power factor, Boost, voltage, low ripple goals. In some way, the power factor is improved.
