A Study on Current-fed Topology for Wireless Resonant Inductive Power Transfer Battery Charging System of Electric Vehicle

In this paper, battery supported transportation systems called electrical vehicles (EV) and the wireless charging topologies are presented. The operation and state of the art techniques for wireless inductive power transfer (WIPT), compensation of IPT techniques, parallel–series (P–S) compensation topology studies are presented. The techniques are majorly based on current fed dc-dc converter topologies. This paper presents the detailed evaluation of electrical parameters, comparison of various qualitative features of power transfer techniques, IPT for EV application, the control strategies and challenges for EV battery charging. The parameters are evaluated and the results are presented in MATLAB/SIMULINK.
