Self-decoupled Dual Pick-up Coils with Large Lateral Tolerance for Roadway Powered Electric Vehicles

Self-decoupled dual pick-up coils for roadway powered electric vehicle (RPEV) with large lateral tolerance and low EMF for pedestrians are proposed. The accurate equivalent circuits and mathematical models for the dual pick-up coils are completely developed to decouple the two adjacent pick-up coils for the both cases with and without core plates. The proposed models are verified by simulations and experiments. It is found that the adjacent pick-up coils can be decoupled regardless of the existence of core plates by overlapping the pick-up coils and the overlapping is nearly same for the both cases with and without core plates.
