Performance assessment of PV energy conversion system with Buck-Boost and Cuk converter for cascaded H-Bridge inverter

The main aim of the paper describes the analysis, modeling and design of a direct control method using incremental Conductance algorithm along with the constant voltage tracking method for a PV system. In this paper the comparative analysis is also done between Cuk and Buck-Boost converter. The PV integration is done with the multistring cascaded multilevel H-Bridge inverter along with hybrid PWM control at the inverter side for a 3KW output power. The main goal of this paper is to integrate PV system with inverter to a grid with better efficiency and lesser total harmonic distortion (THD) by mainly considering the improvement towards the power quality. The simulation results for this proposed work is achieved using MATLAB.
