IMPLEMENTATION OF P & O ALGORITHM FOR MULTI LEVEL CASCADED-BOOST CONVERTER

Abstract

Maximum power point (MPP) monitoring is an unavoidable feature of a solar (PV) array energy conversion system. Thus an attempt is made to  implement the new multi-level cascaded boost converter for maximum power point tracking. MPPT plays  a vital role in Photo Voltaic power system as they provides the maximum power output for PV System for different weather conditions and thereby gives improved array efficiency. The goal is accomplished here by implementing the Perturb & Observe MPPT algorithm, which also provides high voltage gain by the use of the proposed converter circuit. The MATLAB/SIMULINK is used for Testing and Implementing the required objective. The algorithms are implemented in m-file of MATLAB.
