Design and Development of Bidirectional Converter based on V2G and G2V Operation

The rapid growth of electric vehicles (EVs) in the transportation sector presents challenges related to increased peak energy demand on existing grid infrastructures. Vehicle-to-grid (V2G) and grid-to-vehicle (G2V) technologies play a crucial role in mitigating these demands by enabling bidirectional energy transfer. This study proposes a solar-powered bidirectional converter for V2G and G2V operations, facilitating efficient energy exchange between EVs, the grid, and renewable sources. A bidirectional buck-boost converter, integrated with an H-bridge AC/DC converter, is analyzed alongside a control strategy that optimizes power flow. The proposed system leverages solar energy to enhance grid stability and reduce dependency on conventional power sources. Performance and efficiency are evaluated using a MATLAB/SIMULINK-based simulation model under various operating conditions. The results demonstrate the effectiveness of the proposed converter in ensuring stable, efficient, and renewable-powered energy transfer..
