COLLECTOR DEVICE FOR ELECTRIC VEHICLE WITH ACTIVE CANCELLATION OF EMF

摘要

PURPOSE: A collecting apparatus for an on-line electric vehicle is provided to prevent the rapid increase of electromagnetic field by regardless of power transmission from a collector to load. CONSTITUTION: A collecting apparatus for an on-line electric vehicle includes a collecting core(121), collecting coils(124.1, 124.2), and a shielding coil(125). The collecting core is arranged at the bottom side of the electric vehicle. The collecting core is formed into a plane shape. The collecting coils wind around the collecting core. The shielding coils wind around the collecting core to the opposite direction of the collecting coils in order to offset electromagnetic field.
