چکیده :

This paper explores the performance and optimization of an Inductive Wireless Power Transfer (IWPT) system, specifically designed for electric vehicle (EV) applications. The system leverages Self-Oscillating Controlled Inverters (SOCI) and a 2DDP magnetic coupler to achieve high transfer efficiency across a range of operational conditions. The system’s performance is evaluated through simulation results, focusing on key parameters such as the coupling coefficient, transmission distance, and misalignments in both rotational and lateral directions. Results demonstrate a stable efficiency of 92% within the region of freedom (RoF), with the system capable of delivering 1 kW of output power under various misalignment scenarios. The analysis also investigates the impact of transmission distances and lateral misalignments on the coupling coefficient, offering insights into the system’s adaptability. The proposed IWPT system shows promise for flexible, efficient power delivery in dynamic EV charging applications, with the potential for further improvements in real-world deployment.
