Dynamic Wireless Charging of Electrical Vehicles

Electrical and Electronics Engineering

This paper discusses the increasing demand for efficient charging systems due to the rapid growth of electric vehicles (EVs). Dynamic Wireless Power Transfer (DWPT) is introduced as an advanced technology that allows EVs to charge while in motion, eliminating the need for stationary charging systems. The proposed system uses a Super-Twisting Sliding Mode Control (STSMC) technique to improve the performance and stability of wireless charging. The STSMC controller enhances system efficiency by handling uncertainties, disturbances, and variations in load conditions. It improves voltage stability, reduces power fluctuations, and ensures continuous power transfer even when the vehicle is moving. The system is analyzed through simulation by considering parameters such as misalignment, coupling variations, and dynamic loading conditions. Comparative analysis with conventional controllers shows that STSMC provides better efficiency, reduced steady- state error, and improved robustness. The results demonstrate that the proposed system is reliable and suitable for real-time EV charging applications. This research contributes to the development of sustainable transportation by improving wireless charging technology and enabling efficient energy transfer in dynamic conditions.
