CONTACTLESS POWER FEEDING APPARATUS AND CONTACTLESS POWER FEEDING SYSTEM

This abstract first appeared for US patent application 19011773 titled 'CONTACTLESS POWER FEEDING APPARATUS AND CONTACTLESS POWER FEEDING SYSTEM

Original Abstract Submitted

A contactless power feeding apparatus includes a plurality of primary coils mounted on a road and a power feed controller which uses a portion of the primary coils as a power transmitting coil to achieve delivery of electrical power from the power transmitting coil to a secondary coil mounted in a vehicle. The power feed controller uses a selected primary coil that is one of the primary coils other than the power transmitting coil to decrease a leakage of magnetic flux arising from excitation of the power transmitting coil. Instead of the selected primary coil, the secondary coil may be used to reduce the leakage of magnetic flux.
