MPP tracking using IS controller based SEPIC converter

Abstract

This paper presents maximum power point tracking (MPPT) using an intelligence system (IS) based single-ended primary-inductor (SEPIC) converter to operate photovoltaic (PV) system. This paper represents the comparison and improvisation of efficiency with two controllers. The suggested IS is showed to get faster response when compared to the traditional PI controller. It showed high precision during current and irradiation variation and retains the voltage without any changes in the system. The proposed IS based system makes sure that the favorable use of PV system and demonstrates its intended results in different irradiation functions at the output part. The execution of the converter is been tested at different constraints. The execution of the proposed IS based MPP operation of converter will be comparing with the conventional PI based converter. The results in this work is shown that the IS based MPP scheme for SEPIC will be tracking the accurate reference signal and as well as the transfer power more than that of the conventional PI based system. Compare to the PI based system the FLC has improved its efficiency about 3% in this work. In this paper the Simulink model is been built in MATLAB 2013a Version is used to get the result.
