Simulation and Hardware Implementation of Incremental Conductance MPPT Using Self Lift Cuk Converter

M. Latha Devi, Mr. M. Chilambarasan, M.E.,

This paper presents design and simulation of incremental conductance (IncCond) Maximum Power Point Tracking (MPPT) using self lift cuk converter. The solar panel model is developed using the basic circuit equations of photo voltaic cell. The MPP of a solar panel varies with irradiation and temperature. The IncCond algorithm is used to track the maximum power from the solar panel. The unregulated voltage from the panel will be regulated by using the self lift cuk converter. It will reduce the voltage and current ripple. As for component stress the self lift cuk converter has a smaller voltage and current stresses than the original cuk converter. Matlab/Simulink was used for simulation studies.Index Terms— Microcontroller, Incremental conductance (IncCond) maximum power point tracking (MPPT), self lift cuk converter, photovoltaic (PV) system.
