SAR Dependence on Phantom Dimensions in WPT Exposure Assessment
説明
The concept of wireless power transfer (WPT) for distant powering of various electronic devices has received much attention of the research community [1]. Recently, WPT technology has been actively developed for the electric vehicle charge applications [2]. According to the ICNIRP guidelines, the human exposure limits above 100 kHz using the specific absorption rate (SAR) as the assessment criteria are defined [3]. In human safety assessment of inductive coupling WPT systems, phantom of different shapes and dimensions can be used [4]. It is therefore important to consider the effect of phantom size variation on the SAR values obtained in the assessment of WPT systems. This work reports the results of EM simulation of a simple inductive coupling WPT coils operating close to the elliptical phantoms of varying dimensions.
