Abstract:-As the population increases and people continue to demand a higher standard of living, the demand for energy also continues to increase. Thus there is a rapid growing interest in renewable energy, such as fuel cells and photovoltaic systems in the distributed power system architecture. Innovative topologies for renewable energy conversion systems that integrate with electric grids and energy storage systems are being proposed, each with limited modes of operation for the various needs in smart grid applications. In the view of this, bidirectional power flow plays vital role in grid connected systems. In vehicle-to-grid (V2G) systems, electric vehicles interact with the grid as distributed energy storage systems that offer many potential benefits. As an energy Interface between a vehicle and the grid, the bidirectional converter plays a crucial role in their interaction. Its reliability, safety, cost, efficiency, weight, size, harmonics, and other factors are of essential importance for V2G realization, especially for on-board operations. Beyond the common existing topologies for bidirectional converter, this paper brings out a comparative study of different types of bidirectional converter which are used in grid connected systems with highlighting the features of each converter for rooftop solar generation and hybrid power system in small scale renewable generation.
