In this paper the increment of voltage and reducing the stages of the hybrid system is presented. The hybrid
PV-wind-battery based system for household applications, which can work either in stand-alone or grid connected mode.
This system is suitable for household applications, where cost is low, simple and compact system capable of autonomous
operation is desirable. The proposed system has a transformer coupled full bridge converter fused with a bi-directional
buck boost converter and voltage doubler and a single phase full bridge inverter. The proposed converter has reduced
number of power conversion stages with less number of components and high efficiency compared to existing system.
The bi-directional buck boost converter fused with full bridge inverter helps in harnessing the power from solar and wind
is connected on primary side of multi input transformer whereas voltage doubler and single phase full bridge inverter
connected on secondary side. A full bridge inverter and voltage doubler circuit helps in increasing the voltage and
reducing the size of the transformer. Thus, it improves the efficiency and reliability of the system. Simulation results
obtained using MATLAB/Simulink show the performance of the proposed system under various modes of operation.
