High-Voltage Gain Bidirectional Z-Source DC-DC Converter for Efficient Vehicle-to-Grid (V2G) and Grid-to-Vehicle (G2V) Applications

This paper presents an analysis and working of a high-voltage gain switched Z-source bidirectional DC-DC converter for single-phase Vehicle-to-Grid (V2G) and Grid-toVehicle (G2V) applications. The focus is on power conversion technologies and control methods to facilitate two-way charging between electric vehicles (EVs) and the power grid. The converter enables efficient energy transfer, helping to manage peak load demands, stabilize the grid, optimize energy use, and integrate renewable energy sources, ultimately providing economic benefits. The work explores the development of efficient bidirectional Z-source converters and their integration into EVs, supporting both V2G and G2V functionalities. The primary goal is to examine the working of this converter, which contributes to the advancement of smart grid technologies, ensuring the seamless integration of EVs into the power grid and vice versa, promoting a sustainable transportation future. By combining advanced bidirectional switched converter designs with control algorithms, this study achieves fast operation switching, different mode operations and reducing system complexity. Simulation results validate the proposed converter's effectiveness for V2G and G2V operations.
