Analysis of electromagnetic field leaked from wireless power transfer system in case-study house

The wireless power transfer (WPT) system has been actively developed in recent years. Since the electromagnetic field leaked from the WPT system may cause a false operation of other electronic devices, an analysis of the leaked electromagnetic field is significant issue for its practical realization. This paper presents that the electromagnetic field leaked from the WPT system installed in a case-study house is evaluated in the measurement and simulation. The WPT leakage emulator that can generate the electromagnetic field leaked from the WPT system is used in the measurement. The suitable calculation algorithms with respect to three frequency bands that cover the high-harmonic component of the leaked electromagnetic field are applied for the simulation. Moreover, the significant improvement of the simulation speed is achieved using the supercomputer. The evaluation results of the leaked electromagnetic field distributions at four positions in the case-study house show the validity of the simulation compared with the measurement.
