SEPIC converter based MPPT controller for SPV module under partial shading condition

The increasing in the use of distributed generation with traditional power generation system leads to continuous evolution of power electronic interfacing system. This paper deals with some of the most crusial aspects of power electronic converter i.e. detection of fundamental frequency and its components for grid interfacing of the converter. The paper proposes SEPIC converter technology with Maximum power point tracking system so as to extract the maximum amount of power from solar cell by operating it at slope tending towards zero. The paper presents a detail description and validation of solar photovoltaic system under partial shading condition with multiple peak of P-V and I-V curves. MATLAB based modelling and simulation scheme was used, which solves the multiple peaks problem and track the global point.
