The Modeling and Simulation of Active Power Factor Correction System Based on MATLAB

Active Power Factor Correction (APFC) is widely used in AC/DC converters to eliminate harmonic distortion and improve power factor. And new control strategies and techniques could enhance the goals above. By using MATLAB/SIMULINK, the function simulation and verification of the research object can be obtained. The verified model can be automatically transferred to the target microprocessor code by MATLAB to perform the control strategy in real world. Thus the efficiency to develop a new control strategy improves a lot. In this paper, the function simulation and verification of APFC system based on MATLAB is introduced. This fully prepares for future control strategies running on DSP.
