Electromagnetic interaction between multiple inductive power transfer systems

This paper analyzes and simulates the electromagnetic interaction between multiple inductive power transfer (IPT) systems for electric vehicle charging applications. A simple car model is built up in 3D Maxwell simulation to reduce simulation time and calculate leakage magnetic field between two cars. The impact of phase difference between two IPT systems is investigated. Passive shielding methods are used to reduce the leakage field in space between two cars.
