Maximum Power Point Tracking using SEPIC converter with improved Sliding Mode Controller

ABSTRACT Over a few decades, there was lot of advancements on innovative source of energy. Globally increasing demand for electricity is a major concern. Among the sources available on earth, solar energy is the most promising and naturally available source on the earth. Major drawbacks of variable solar energy are due to irradiation and temperature. This project presents Maximum Power Point Tracking of Photo voltaic system rely on Sliding Mode Control unit. This project proposes the modest Sliding Mode Controller which is generally used to uphold the performance of solar array power tracking. The tool Matlab 2013 is used for evaluating. The proposed system is about improving the output power of solar system by SEPIC converter and additional circuit.
