Applications of wireless power transfer (WPT) systems to electric vehicles have been studied intensively in recent years. There have been so far many examples of exposure assessment of wireless power transfer (WPT) systems by using numerical methods. However, there was a few of exposure assessments by real experiments. In this study, we constructed a WPT system for 100 kHz-band frequency. We also characterized our constructed WPT system by measuring the power transfer efficiency of the system and the magnetic field distribution around the system. We have confirmed that the measured magnetic fields agree well with those obtained by numerical simulations using the method of moments. Then, we calculated the induced physical quantities inside a simplified human model which is placed close to the WPT system. Finally, we calculated the maximum allowable input power into the WPT system when the simplified human model is placed nearby the system. As a result, the maximum allowable input power is mainly restricted based on the guideline levels for electrical-stimulation effect rather than those for heat effect. |
