EMC issues on wireless power transfer

Wireless power transfer technology is expected to be one of key technologies to offer easy and safe power supply as well as battery charging and thus to contribute to smart community through various kinds of products, such as portable digital devices and electrical vehicles. This paper mainly focuses on EMC issues on wireless power transfer, including emission which may cause the interference to other radio equipment, immunity, and human body protection. The general overview on the EMC and relevant issues are shown. The current and ongoing effort of technological research, rule making, and international and regional standardization on EMC aspects of wireless power transfer are also described.
