Single-Phase Boost PFC Simulation Model

I have developed a single-phase Boost Power Factor Correction (PFC) simulation model using MATLAB, achieving a power rating of 11kW. The model implements a dual-loop PI digital control strategy that effectively regulates both current and voltage loops, ensuring excellent waveform stability and precision. This control approach incorporates discrete PI controllers in both inner current loop (for fast dynamic response) and outer voltage loop (for steady-state accuracy). During simulation testing, the model demonstrates outstanding performance with reliable operation characteristics. The implementation includes proper sampling frequency selection, anti-windup mechanisms, and duty cycle limiting to maintain system stability. Through multiple test iterations and optimization processes involving parameter tuning and boundary condition validation, I have ensured the model's reliability and stability for practical applications. Therefore, this model can provide substantial support and assistance for research and development activities in related power electronics fields.
