A study of magnetic coupling and selection of operating frequency for static and dynamic EV charging system

Abstract

In this paper analytical study have been undertaken to relate the operating frequency of the inverter in inductive power transfer system used to charge the electrical vehicle that is free to move. The distance varies the mutual inductance of the pickup coil and the resonance frequency of Inductive Power Transfer system. The study also shows the maximum power transfer is achieved by the appropriate choice of inverter operating frequency and depends on the distance between the pickup coils. The analytical results have been numerical validated using MATLAB. The inverter operation and its frequency dependency for maximum power transfer for varying distance between the pickup coils have been verified through simulation.
