Abstract:This paper presents an innovative solution for the enhancement of the single-stage photovoltaic systems grid-tied topology. The proposed approach involves the integration of an Active Power Filter (APF) with a Quasi-Z-Source Inverter (qZSI) that are controlled by a modified Synchronous Reference Frame (SRF) approach. Indeed, the conventional grid-tied PV systems often face challenges such as grid instability, harmonic distortion, and power quality issues. These issues can lead to inefficient energy transfer an… Show more
