In this proposed methodology a Hybrid power system combining the PV Module, wind energy source and a battery source to supply remote areas more effectively. This hybrid system synchronizes the PV module, battery and wind source using a modified bidirectional multi input dc-dc boost converter. This converter drive load and utilize the power generated from the hybrid power system more efficiently. This Hybrid power system by definition contain a number of power generation devices such as wind turbines based energy sources, photovoltaic source, micro-hydro and also fuel generators as input sources for power generation. However the proposed three input boost converter is applied to hybridize a PV, WIND energy, and a battery storage scheme. Four liberated duty ratios of the converter facilitate power flow between input sources and the load. This converter has the merits of making use of a low voltage battery. The inherent nature of this converter eliminates the need for separate input filters for PFC. The multi –input converter providing simple circuit topology, centralized control of power flow is bidirectional in this converter.
