NON-CONTACT ELECTRIC POWER SUPPLY DEVICE

摘要

A non-contacting sudden charging apparatus is provided to decrease the magnetic flux density by combining a flat board type magnetic core with a flat spiral coil. A non-contacting sudden charging apparatus supplies power from a primary coil(7) to a secondary coil(8) based on the mutual induction of an electromagnetic induction. The first coil and the second coil have structures which are wound on the same plane flatly and spirally. The first coil is buried in a first magnetic core(13) and the second coil is buried in a second magnetic core(14), respectively. Each of the magnetic cores forms a flat board shape.
