The Wireless Power Transfer (WPT) has been drawing the attention as a technology for charging an electric vehicle and a mobile equipment in a non-contact manner. Since the WPT system utilizes the high-frequency power, there is a concern related to the interference to the broadcasting and the wireless communication due to the unnecessary radiated emission, etc. Therefore, except for some systems, it is necessary to satisfy the Electro-Magnetic Interference (EMI) allowable value of the high frequency utilization equipment in accordance with the Article 65 of the Radio Equipment Regulation and to obtain the installation permit. We have developed the electric field resonance type WPT system with a frequency of 13.56 MHz and an output power of 1 kW that satisfies the EMI allowable value specified for the high frequency utilization equipment and have obtained the installation permit.
In this paper we will report the various characteristics of this system.
