the single stage converter is introduced in the proposed work. The output from both the systems are given to the fly-back converter it will give the constant dc voltage as the output. By controlling the switching period of the converter switch the output can be controlled. The figure shows the interfacing of hybrid system using individual dc-dc converter. Fig.6 Hybridization using individual boost converters VI.SIMULATION RESULTS The Fig.5 shows the block diagram of single stage converter for the proposed hybrid system. In the existing system two individual dc-dc converters were used for controlling the power flow; which will increase the number of circuit components. To reduce this, single stage conversion is used. The output from both wind and solar system is given to the fly-back converter unit. This will carry out the proper conversion for the required output. In this hybrid system Solar array is considered as a main source and wind will operate parallel to this. The conduction period of the switch is varied accordingly to the output required. In the single stage conversion no ma...
