The integration of Electric Vehicles (EVs) into microgrid-based renewable energy systems presents significant challenges related to power conversion, energy management, and system stability. Efficient power electronic converters and control strategies are essential for optimizing energy exchange between Renewable Energy Sources (RES), EVs, and the grid. This review examines various DC-DC converters, analysing their efficiency and impact on system performance. Additionally, it explores different control techniques, assessing their effectiveness in regulating power flow and ensuring stable operation. The findings highlight the role of converter design, and control approaches in enhancing the efficiency and reliability of microgrid-based EV systems. This study provides significance into emerging technologies and methodologies that support the uninterrupted integration of RES and EVs, contributing to the development of sustainable and resilient power infrastructure.
