Advanced wireless electric vehicle charging system with cascaded fuzzy control and multi-stage rectification

Abstract

The growing demand for electric vehicles (EVs) has intensified the need for high-efficiency, reliable, and user-friendly wireless charging systems. Conventional wired chargers and existing wireless solutions often suffer from high losses, poor power quality, and limited control accuracy under dynamic operating conditions. To address these challenges, this paper proposes an advanced wireless charging architecture integrating a three-phase Vienna rectifier, high-frequency inverter, and isolation transformer. A three-phase frequency inverter and a three-stage synchronous rectifier further enhance conversion efficiency. Precise voltage and current regulation is achieved using a cascaded fuzzy controller (CFC) combined with a proportional-integral (PI) controller. MATLAB simulations demonstrate unity power factor, improved efficiency, and stable performance under varying load conditions. The results confirm that the proposed architecture offers a scalable, robust, and energy-efficient solution capable of advancing EV charging infrastructure and supporting sustainable transportation.
