MATLAB Simulation Application of APFC with Implementation Approaches

This article discusses the MATLAB simulation application of Adaptive Power Factor Correction (APFC). The simulation demonstrates flawless operation and serves as a valuable reference resource for understanding APFC working principles. Notably, the implementation includes average current mode control, which is crucial for power system stability and reliability. Through detailed examination of this MATLAB simulation, we can better understand power systems and contribute to their design optimization. The simulation employs key MATLAB functions such as Simulink blocks for power electronics components, PID controllers for current regulation, and measurement blocks for real-time power factor calculation. The code implements phase-locked loop (PLL) techniques for synchronization and uses switching frequency optimization algorithms to minimize harmonic distortion. The model demonstrates practical implementation of voltage and current feedback loops with appropriate sampling rates and control system tuning parameters.
