NON-CONTACT TRANSMISSION APPARATUS

摘要

A non-contact transmission apparatus includes a primary coil for transmitting a power or a signal by a magnetic coupling; and a secondary coil for receiving the power or the signal, the coils being arranged to oppositely face each other. The coils are arranged in a reference pattern or one or more deviated patterns where the position of the secondary coil with respect to the primary coil is different from that in the reference pattern, and at least one of factors is set such that a coupling coefficient between the coils in the reference pattern is identical to that in each of the deviated patterns, the factors having inner or outer diameters of the coils; a relative position between the coils on a plane that is in parallel with oppositely facing surfaces of the coils,- and an angle at which the secondary coil is inclined with regard to the primary coil.
