Load Independent Characteristics of Dynamic Wireless Charging System Through Higher Order Compensation

Dynamic wireless charging (DWC) system for EVs is the heart throb signal for future transportation. In this work load independent characteristics (LIC) are investigated for the proper operation and suitability of a dynamic wireless charging system. Considering the aspects of constant current, constant voltage and zero phase angle (ZPA) power source, the characteristics and performance of LIC are analyzed to estimate the efficiency of the DWC system for an electric vehicle. The simulation study has been carried using MATLAB software and it is found that simulation results are closely matched with the analytical findings. Further, the variation of efficiency is presented with respect to the variation of mutual inductance as well as load resistance.
