A Single-Stage Bridgeless PFC Charger with Enhanced Power Quality for LEV Mounted Solar PV Panel

This paper presents the single-stage bridgeless PFC charger for LEV Mounted Solar PV Panel with improved power quality. A light electric vehicle mounted PV panel is one such expanding sector. Power factor corrected (PFC) charger presented in this paper focuses on the same and interfaces with grid, PV panel and battery to form a three-port topology. Both grid and PV panel can charge battery independently as well as in synchrony. It aims to improve the total harmonic distortion (THD) of source current in compliance with the IEC 61000-3-2 standard and reduce the total number of components. A variable step-size maximum power point tracking (MPPT) technique provides perturbation-free output from PV panel in steady state. It is intended to operate optimally even in dynamically challenging situations, including sudden changes in grid voltage, broad variations in output power demand and unexpected disruption in one of the power inputs. The Simulation results can be evaluated by using MATLAB/Simulink software.
