Mohamed Rabik, M. Nandhini and J. P. Pradeep Department of Mechatronics Engineering, College of Engineering and Technology, SRM Institute of Science and Technology, SRM Nagar, Kattankulathur,603203, Kanchipuram, Chennai, TN, India ABSTRACT This paper presents an inductive power transfer technology for the charging application of an electric vehicle (EV). The inductive power transfer has been an essential and effective way of transferring power to EV on the run. The frequency mismatch in between primary and secondary of inductive coupling is a major problem under a dynamic load condition of EV. In this paper, a suitable material and coil winding are chosen for primary and secondary coil to meet out the maximum inductive power transfer between the primary and secondary. Hence, a phase locked loop subsystem has been implemented for rectifying the frequency mismatch in between primary and secondary. The range of frequencies for which efficiency have been studied and analyzed under different load conditions. Finally, results have been obtained for a maximum power coupling as compared with conventional wireless transfer schemes.

INTRODUCTION The inductive power transfer (IPT) has started being the future revolutionary technology for power transfer among the battery devices and other contactless power transfer devices and elements to ensure the constant power transfer in the different atmospheric conditions [1]. The electronic manufactures, control devices and automotive industries started adapting the automatic wireless charging technology for electronic applications and vehicles where required.
