Design and Performance Analysis of SEPIC Converter With Different MPPT Control Algorithms For Hybrid Solar-Wind System

In this paper, the simulation model of a Single Input Primary Inductor Converter(SEPIC) with various Maximum Power Point Tracking(MPPT) control algorithms for a hybrid solar-wind system is presented and the performance of the SEPIC converter is studied with those MPPT control algorithms for a DC load(R-Load). The output voltage of a hybrid solar-wind system is weather dependent and intermittent, which is an inherent disadvantage. This problem can be solved by using an MPPT control algorithm-based SEPIC converter which provides interfacing between a hybrid solar-wind system and DC-load. Regardless of variations in weather, it a steady voltage at the output. Separate SEPIC converters have been designed for solar and wind power systems. To get the most power ouof the hybrid solar-wind system, MPPT control algorithms are used.
