DESIGN OF P&O AND FL BASED MPPT CONTROLLERS OF PV ARRAY BY USING POSITIVE SUPER LIFT DC/DC BOOST CONVERTER

Abstract

The electricity which is generated from the photovoltaic (PV) module needs a couple of requirements for utilizing. Firstly, the PV module should work in maximum power point, and secondly, it is needed a power conversion unit. To calculate to Maximum Power Point (MPP) of a PV module or array, solar radiation, ambient temperature, cloudiness ratio, and even wind speed have to be considered. In this paper, the duty cycle of the power conversion unit has been calculated by considering solar radiation. In these calculations, a conventional method which is perturb and observation (P&O), and another approach which is fuzzy logic control (FLC) were studied and compared by using MATLAB/Simulink.
