Design and experimental implementation of single phase power factor correction converter based on fuzzy logic controls techniques

摘要

this paper presents an experimental implementation of the single phase power factor corrector PFC based on AC/DC converter with boost chopper. PI, Fuzzy logic and fuzzy adaptive PID controllers for the capacitor voltage are implemented to improve the performance of the boost converter. A self-tuning filter, used to extract the fundamental component from distorted voltage source, is applied to the Phase Locked Loop (PLL) circuit to get better performance. The robustness of the controllers is verified through simulation in MATLAB/Simulink, the results show that the behavior of the PFC with fuzzy controller is better than the conventional proportional integral PI controller and the fuzzy adaptive PID. An experiment is conducted through a test bench based on dSPACE 1103. The experimental results proved that the proposed controller enhanced the performance of the converter under different parameters variations.
