Design of Modular Flyback Converter for Hybrid Renewable Energy System

Energy scarcity is one of the global issues in day to day life. The demand and consumption are moving head to head which ended up in considerable dependence of non renewable energy resources. The subsequent rise in the price and unavailability of non renewable energy sources aided to rely on the renewable energy resources in order to meet the power demand. Hybrid Energy System is one of the optimal techniques which can be efficiently utilizing the renewable energy resources. As the renewable energy resources depend upon the climatic condition it is difficult to rely upon a single system. In this paper wind and solar Hybrid Energy System is used. The output of the two different energy systems is fed to the modular DC-DC flyback converter in Input Parallel Output Series (IPOS) configuration. The system enjoys the full advantages of modularity like high efficiency and low cost. The flyback converters boost the input voltage from the hybrid energy system. The output of the system is verified using MATLAB/Simulink environment. The stability of the system is also assured due to modularity. The conventional complex powers electronic circuit can be reduced to certain extend. The system efficiency can further improved by using more number of flyback modules and modern control techniques.
