JEE_V3_N2_RP2 Adil Sarwar Journal on Electrical Engineering 2230 – 7176 3 2 11 16 MPPT, Constant Voltage Method, Solar Photovoltaic, Buck-Boost Converter The photovoltaic system exhibits a non-linear i-v characteristic and its maximum power point varies with solar insolation and temperature. An efficient Maximum Power Point Tracking (MPPT) algorithm is important to increase the output efficiency of a photovoltaic (PV) generate system. The first part of this paper intends to give an overview of the Maximum Power Point Tracking methods for Photovoltaic (PV) generators presently reported in the literature. The most well-known and popular methods, like the Perturb and Observe (P&O), the Incremental Conductance (INC) and the Constant Voltage (CV), are presented. These methods, especially the P&O, have been treated by many works. In the second part of the paper, a MATLAB based model of a MPPT by constant voltage method is developed. The simulation results verify the effective implementation of the constant voltage scheme in Simulink. October - December 2009 Copyright © 2009 i-manager publications.
