Real time implementation of unity power factor correction converter based on fuzzy logic

In this paper an analysis and real time implementation of unity power factor correction converter (PFC) based on fuzzy logic controller is studied. A single phase AC–DC boost converter is realized to replace the conventional diode bridge rectifier. Fuzzy logic and hysteresis control techniques is implemented to improve the performance of the boost converter. The fuzzy controller is applied to DC voltage loop circuit to get better performance. The current loop is being controlled by using a PI, and hysteresis controllers. The robustness of the controller is verified via MATLAB/Simulink, the results show that the fuzzy controller gives well controller. An experiment test is implemented via a test bench based on dSPACE 1103. The experimental results show that the proposed controller enhanced the performance of the converter under different parameters variations.

PFC input current Conclusion: In this paper, a single-phase PFC converter DC voltage loop has been analysed. The fuzzy logic controller technique is implemented to improve the performance of the PFC converter, it is robust and efficient. Matlab/Simulink has been used to simulate the proposed techniques with successful result, the dSPACE 1103 have been used to implement the fuzzy controller in real- time. Simulation results have been presented and confirmed by the real time tests; in the same time, high efficiency is obtained. The proposed controller applied to the unity power factor give better results, a reduced harmonic distortion, and robustness control during parameter variations.
