Average Current Controlled APFC Simulation in MATLAB/Simulink

This simulation implements average current controlled Active Power Factor Correction (APFC) in MATLAB/Simulink environment. The simulation results indicate that the system waveforms demonstrate good performance overall, though minor distortion is observed at zero-crossing points that requires further improvement. To address this issue, potential solutions include adjusting control loop parameters (such as PI controller gains) or implementing advanced control strategies like predictive current control or fuzzy logic compensation. The Simulink model utilizes key blocks including current measurement sensors, voltage controllers, PWM generators, and power electronic switches to achieve power factor correction. Additional system optimization could involve enhancing the switching frequency management or incorporating harmonic compensation algorithms to improve overall performance. These implementation approaches provide practical guidance for power electronics engineers working on APFC system design and refinement.
