The number of electric vehicles (EVs) on the road has increased considerably in recent years due to the rapid development of EV technology. This surge in EV adoption has led to an increased demand for effective Vehicle-to-Grid (V2G) systems that can enable BiDirectional Power-Flow (BDPF) between EVs and the grid. Bi-directional Power Converters (BPC) play a crucial role in facilitating this bi-directional energy transfer, ensuring efficient power management and enhancing the overall performance of V2G systems. This work aims to explore the potential of various bi-directional power converters, including Bi-directional DC-DC Converters (BDC), Resonant-Converters (RC), Multi-Level Inverters (MLI), Bidirectional-Resonant Converters (BRC), Multi-Level Bi-directional DC-DC converters (MLBDC), Multi-Level-Converters (MLC), and Multi-Level Bi-directional ResonantConverters (MLBRC), in V2G electric vehicle systems. The literature survey reveals the advantages and challenges associated with each type of converter.
