ABSTRACT
The rapid growth of electric vehicles (EVs) and renewable energy integration has increased the need for advanced charging infrastructure that is reliable, flexible, and user-friendly. Wireless power transfer (WPT) technology has emerged as a promising solution for autonomous EV charging, especially when combined with renewable energy hubs such as solar and wind-based microgrids. Wireless power converters play a central role in enabling efficient energy transfer without physical connectors, improving safety, reducing maintenance, and supporting autonomous operation. This paper presents a comprehensive review of wireless power converter topologies, operating principles, control strategies, and system architectures for EV charging and renewable energy hubs. Both stationary and dynamic wireless charging methods are discussed, along with resonant converter designs and high-frequency power electronics used in WPT systems. Challenges related to efficiency, misalignment, electromagnetic compatibility, and grid integration are analyzed. Recent research trends and practical deployment issues are also highlighted. The study concludes that wireless power converters, when integrated with renewable energy hubs, can significantly enhance the sustainability and autonomy of future EV charging networks.
