DESIGN AND OPTIMIZATION OF HIGH-FREQUENCY POWER CONVERTERS FOR ENHANCED EFFICIENCY AND PERFORMANCE IN ELECTRIC VEHICLE APPLICATIONS

Abstract

The paper reviews high-frequency converter innovations for electric vehicles and renewable power systems with a focus on sustainability and energy system improvement. Using the PRISMA 2020 methodology, 73 excellent research spanning 2014 to 2024 was evaluated for new converter models and advanced materials and control methods and future trends. The research field produced vital findings showing how converter topologies advanced with the invention of LLC resonant designs and dual active bridges enabling soft switching and enhanced scalability and efficiency. Silicon carbide and gallium nitride function as wide-bandgap semiconductors which enable developments in power density while improving compactness along with thermal control capabilities. Efficient operation and stability enhancement in microgrids together with vehicle-to-grid systems result from implementing adaptive and AI-based control techniques. Power conversion along with system reliability improvements become possible through converter applications in wind and solar power systems. The upcoming opportunities align hybrid and multipurpose systems by connecting smart control techniques featuring artificial intelligence platforms with digital twin systems to renewable energy and electric vehicles storage units. These innovative developments establish high-frequency converters as revolutionary energy solutions to address global power issues while advancing environmentally sustainable power generation and locomotion systems. This paper includes essential details about present research along with prospective paths for science advancement. Advanced control methods such as sliding mode control and predictive control together with AI-driven adaptive strategies remain essential for this research because they guarantee stable operation of intricate networks. These approaches deliver three substantial benefits for renewable microgrids including dynamic load control and harmonic reduction with maximum power flow enhancement for V2G systems. The technology behind digital twins positions itself as a major growth opportunity because it delivers live system tracking alongside predictive equipment care and works to spot issues early
