I. Introduction
With the expansion of current research interests and anticipated further increases in the use of wireless charging systems by inductive power transfer (IPT) for electric vehicles, it is important to dedicate research efforts to interactions between the wireless charging systems and the human body [1], [2]. This research paper is mainly motivated by two factors. One is to evaluate the induced EMFs in the human body at the frequency of the wireless charging system, i.e., magnetic flux density, electric field, and current density, to evaluate the potential health effects as well as examine the compliance with standards defined by International Commission on Non-Ionizing Radiation Protection (ICNIRP) [3]. The other factor is to investigate the influence of the input current of the wireless charging system on the radiation levels and provide the valid data for determining the extent of design freedom of IPT systems.
