In this paper, a novel resonant reactive shield using modified phase shifter to reduce the magnetic field leakage for wireless charging electric vehicle is proposed. The proposed shield generates the cancelling magnetic field of which phase is completely opposite to that of incident magnetic field. By simulation, it is verified that the proposed reactive shield has significantly improved shielding...
In this paper, the electromagnetic compatibility issues of wireless powered electric vehicle are discussed in the view of electromagnetic field and electromagnetic interference. The magnetic field reduction for human exposure for near field is investigated and the definition of electromagnetic interference measurement is discussed.
Recently, KAIST has introduced the novel on-line electric vehicle (OLEV), in which the automotive vehicle constantly receive and recharge their power from the power lines embedded underneath the surface of the road. OLEV has the reduced battery capacity to about 20% compared to that of the conventional battery-powered electric vehicles, while it can consequently minimize the weight and the price of...
In this paper, we introduce the On-line Electric Vehicle (OLEV) system and its non-contact power transfer mechanism and propose some techniques for the reduction of electromagnetic fields (EMFs) from the power line and the vehicle itself. By applying a metallic plate shield, horizontal/vertical shield, and connecting wire for loop cancellation, the low frequency EMFs have been significantly reduced...
