Abstract :
The wireless power transfer (WPT) system has been actively developed in recent years, and the interference to the other devices that is caused by the electromagnetic field leaked from the WPT system has also been discussed. In this paper, we propose the WPT leakage emulator that is extremely usable to quantitatively evaluate the interference and the leaked electromagnetic field distribution. The WPT leakage emulator that is composed of only a primary coil can easily reproduce the electromagnetic field leaked from the various types of WPT system by adjusting the coil configuration, input power, and the operating frequency appropriately. The WPT leakage emulator that operates at 85 kHz and 6.78 MHz is fabricated, and the fundamental operation and its operating mechanism are demonstrated in both the measurement and the simulation.
