| Abstract(E) | A wireless power transfer system(WPT) for electric vehicles(EVs) needs to be evaluated in its leakage electromagnetic field (EMF). It is generally determined to be measured at 10 m point when the maximum rated power is transmitted between full-scale coils. In this paper, we propose a novel evaluation method of the EMF using a coil scaling law. During the development period, the mini-scale coils can be used to verify the leakage electromagnetic field, and the full-scale coil only needs to be finalized to ensure that it satisfies the regulations, thus shortening the verification time and reducing the cost. In order to realize the above, the conditions that enable equivalent evaluation of full-scale and mini-scale coils were derived. |
