MAGNETIC FIELD CANCELLATION WIRING DEVICE AND ACTIVE CANCELATION CONTROL SYSTEM AND ON-LINE ELECTRIC VEHICLE COMPRISINGING THE DEVICE AND ACTIVE CANCELATION CONTROL METHOD OF ON-LINE ELECTRIC VEHICLE

摘要

PURPOSE: A current collecting device with a cancellation coil unit, a shielding system which selectively cancels an electromagnetic wave, an on-line electric vehicle with the current collecting device, and a method for cancelling the electromagnetic wave of an on-line electric vehicle are provided to analyze distribution of an unnecessary magnetic field occurring in an on-line electric vehicle, thereby completely cancelling the unnecessary magnetic field. CONSTITUTION: A magnetic field is induced by the flow of currents in a metallic bar(200). A current collecting unit(300) generates an induced current in a current collecting coil. A cancellation coil unit(400) is wound on a cancellation coil of each end of the metallic bar and cancels an electromagnetic wave occurring an on-line electric vehicle.
