Abstract
This paper discusses the simulation and experimental validation of a curative solution, called power factor correction (PFC), intended to improve the power quality of the single-phase AC/DC converter. A modern control law combined between two methods which are the fuzzy logic theory and the predictive technique is proposed in this research work. The first is reserved to guarantee an intelligent regulation of the DC output voltage while the second aims to the intuitive power switch governance of the boost chopper constituting the PFC. The adopted solution ensures the delivery of a source current of sinusoidal shape, respecting the imposed international standards and the operation of the treated system under a power factor very close to unity. The effectiveness and practical use of the intelligent intuitive PFC control have been experimentally proven using the dSPACE 1104 card for different operating conditions, resulting from the variation of the load and the reference output voltage. The practical results in terms of power quality identified by a total harmonic distortion of the source current of 2.8% and a power factor of 0.995 respect the international standard IEEE 519-2014. Also, they are very convincing compared to those existing and recently published in the literature.
