Bidirectional Ac/Dc Converter Topologies: A Review

High penetration of renewable energy generation has demanded advancements in grid interfacing technologies. Further, battery energy storage systems, vehicle to grid and grid to vehicle concepts are emerging as solutions to the grid instability due to intermittent nature of renewable sources. Therefore, it is very important to have an advanced bidirectional interface between the grid and the source to maintain the quality of power supply. AC/DC bidirectional power converter is one of the major and an essential component in the bidirectional link. This paper investigates existing AC/DC bidirectional converter topologies, their pros and cons and recent developments to improve the performance.
