Magnetic Design of a Three-Phase Wireless Power Transfer System for EMF Reduction
Abstract
Wireless charging of electric vehicles (EV) by means of the wireless power transfer (WPT) is becoming increasingly popular in the recent years. And the electromagnetic field (EMF) should be lowered for the safety of pedestrians. In this paper, a new three-phase WPT structure is proposed. It is compared with the single phase WPT structure to demonstrate the advantages of the proposed structure in the magnetic field distributions and system performance. The simulation results using the 3D finite element analysis (FEA) tool show that it can considerably suppress the leakage magnetic field from the WPT system with the enhanced performance.
