Modeling and simulation of integrated CUK converter for grid connected PV system with EPP MPPT hybridization

Abstract

This paper presents the modeling and simulation of integrated CUK converter with EPP MPPT for grid connected photovoltaic system. Integrated CUK converter is presented for the use as a high gain boost (step- up) converter whose switch operates in continuous conduction mode. MPPT controllers are used in PV system to track the maximum power due to its poor efficiency. The system is designed in MATLAB/SIMULINK and the simulation results shows the comparative analysis of high gain integrated CUK converter with conventional CUK converter for grid connected photovoltaic system.
