Modeling and simulation of incremental conductance MPPT using self lift SEPIC converter

This paper presents the modeling and simulation of incremental conductance (IncCond) Maximum Power Point Tracking (MPPT) using self lift Single Ended Primary Inductance Converter (SEPIC). The solar panel model is developed using the basic circuit equations of photovoltaic 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 SEPIC converter. It will reduce the voltage and current ripple. As for component stress the self lift SEPIC converter has a smaller voltage and current stresses than the original SEPIC converter. Matlab/Simulink was used for simulation studies.
