Analysis of maximum power point tracking techniques for photo voltaic system

Solar energy is the most efficient and emerging renewable energy source available. The Photo Voltaic Systems are the most abundantly used solar energy converters. Maximum power point tracking (MPPT) plays vital role in Photo Voltaic system because it maximize the output power from a solar system for a given set of conditions, and hence improves Photo Voltaic efficiency. This paper presents maximum power point tracker control technique using Fuzzy Logic Controller and is compared with Incremental Conductance as one of the most widely used conventional method. Both the techniques have been analyzed and simulated to generate the optimal voltage and power from the PV system by the DC-DC boost converter by modulating the duty cycle.
