PROJECT TITLE :

Design of a Sliding-Mode-Controlled SEPIC

ABSTRACT:

This paper describes how to create a sliding-mode controller for photovoltaic (PV) systems that tracks the maximum power point. However, it is applicable to a wide range of converters that can be used for PV applications, such as a single-ended primary inductor converter, which has a fourth-order topology. There are a number of design inequalities that must be met in order to achieve the intended closed-loop converter's performance under these conditions. With the method described in this study, the superiority of the control strategy over traditional tracking methods may be shown analytically. Both simulations and experiments have been used to verify the analytical results.
