Abstract

Wireless power transfer (WPT) technology is a promising approach to easily charging the batteries of electric vehicles and plug-in hybrid vehicles. WPT systems that use magnetic coupling generate a surrounding magnetic field, and it is beneficial to reduce this magnetic field from the viewpoint of electromagnetic compatibility. We propose a magnetic field reduction method using magnetic field canceling coils and conductive plates. This method can reduce the magnetic field far from the WPT system without reducing the coupling factor.
