Performance Analysis of Positive Lift LUO Converter

Abstract

The quick depletion of remnant fuels, environmental pollution has become more solemn matter. Recently a good deal effort made to find renewable energies and solar energy is the ideal solution. In photovoltaic arrays, cells are arranged in series to obtain the required voltage. The output characteristic feature of photovoltaic array show a discrepancy radically by way of solar irradiation, temperature and presents MPP under various atmospheric nominal conditions. Based on Perturbation and Observation method, MPP is tracked for PV. The DC-DC converter is used to improve the output voltage and are widely used in solar energy conversion systems.. Here ultra-lift LUO converters are normally used to convert low input voltage in to high output voltage (same principle of Boost converter). But these converters are not stable in voltage lift and less reliability. By using Voltage lift method, voltage transfer gain higher than other classical converters is obtained.
