Abstract

This paper deals with the simulation of human exposure to magneto-quasistatic fields of Inductive Power Transfer (IPT) systems. Since the applicability of direct eddy current field solvers for such problems becomes disputable when the scale and/or the resolution of geometries increase, both the Scaled-Frequency FDTD method and the Scalar-Potential Finite Difference (SPFD) approach are extended and used here. Numerical examples for the verification of the procedures and an application including shielding effects in nearby conductive structures are presented. The results are compared to the limits recommended by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).

汽车低频感应功率传输系统高分辨率剂量学模拟的数值格式
本文研究了感应功率传输(IPT)系统中人体暴露在准静态磁场中的模拟。由于当几何图形的尺度和/或分辨率增加时,直接涡流场求解方法的适用性变得有争议,因此本文扩展并使用了标频FDTD方法和标势有限差分(SPFD)方法。给出了数值算例,验证了该方法的正确性,并给出了一个包括附近导电结构屏蔽效应在内的应用。该结果与国际非电离辐射防护委员会(ICNIRP)建议的限值进行了比较。
