An improvised p & o method for extracting maximum power in pv applications with moving average filter using a boost converter

Abstract

As the population is growing, there is a rapid utilization of electric energy either in industries or house-hold sectors. Due to scarcity in conventional energy resources could not meet the power demand. Non conventional energy combining with conventional resources are needed for satisfying the energy demand. The best alternative is the Solar energy. In order to extract large amount of power from incoming solar emission an optimized and redundant control strategy is developed to remove the existing straits. From photovoltaic module maximum possible power is extracted using MPPT and it is fed to the step up converter which boosts up the voltage and later given to load. Modified Perturb & Observe method regulates duty cycle of step up converter for changing load in accordance to MPPT tracking.
