Simulation of Photovoltaic based DC-DC Converter Topologies

Abstract

Due to the depletion in the fossil fuel there is the major requirement of using other sources of energy.This concern has lead to the use of sources such solar energy,wind energy ,fuel cell etc.Power electronics is gaining popularity due to reduced cost and awareness in the society regarding the green environment .DC-DC Converters are required to convert the supply according to load demand .In this paper advancement in the topologies of DC-DC Converter is discussed and implemented using power sim environment. Photovoltiac system is used as the source. To extort utmost power from photovoltaic systems, utmost power point technique is used . Different topologies such as Buck ,Boost,Buck-Boost ,cuk ,zeta using solar as input are implemented and compared in this paper. as each topology has different complexities,efficiency.the work is carried using Psim
