ABSTRACT:
A system for supplying electric power to an electrically powered vehicle includes a feeder disposed along a structural member as a guide rail that guides the vehicle. The vehicle has an electric power receiving unit that receives electric power from the feeder on a non-contact basis. The electric power receiving unit has a ferrite core with a coil. A ferrite sheet is disposed on a surface of the structural member in such a manner that the ferrite sheet is opposite to the electric power receiving unit. The feeder is surrounded by the ferrite core and the ferrite sheet. When an AC current is supplied to the feeder, a magnetic flux that penetrates the ferrite core and the ferrite sheet varies, thereby causing electromotive force to occur in the coil.
