CONTACTLESS POWER TRANSFER APPARATUS, INDUCTIVE POWER SUPPLY APPARATUS AND INDUCTIVE POWER COLLECTION APPARATUS AND MOVING OBJECT USING THE SAME

摘要

PURPOSE: A feeder of a magnetic inductive mode and a non-contact electric power transfer device are provided to charge a battery with a contactless method by transmitting electricity without mechanical contact with a power transmitter. CONSTITUTION: A non-contact electric power transfer device(100) comprises a feeding unit(100a) supplying electricity with a magnetic inductive mode, and a current collecting unit(100b) receiving the electricity. The feeding unit comprises a feeding power source(116) supplying the electricity, a feeding core(112) for offering a path of magnetic flux, and an electric supply unit(110) including a feeding cable(114) which is wound in around the feeding core. The electric supply unit is electrically connected to the feeding power source. The current collecting unit is coupled with the electric supply unit. The current collecting unit comprises one or more concentrator units(120) having a concentrator cable(124), a concentrator circuit(130), a driving part(140), and a controller(150).
