Analysis and Comparison of PV Array MPPT Techniques to Increase Output Power

In context of renewable energy the attention towards solar energy has increased as the p-v characteristic of photovoltaic cell is non-linear. In order to get the maximum output from photovoltaic system, the MPP must be tracked down without any break and for this we have large number of MPPT techniques, this paper shows the most widely used algorithms such as P&O, Ic technique, Ripple Correlation Control, Current sweep, particle swarm optimization, Fuzzy logic etc. These mppt algorithms are investigated and then compared on various parameters such as efficiency, number of sensors, cost etc and displayed in tabular form. The results of simulation are designed with the help of MATLAB-Simulink.
