Title:
NON-CONTACT POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/011726
Kind Code:
A1
Abstract:
A non-contact power supply system comprises: a power supply device which includes a plurality of primary coils which are excited with an operating frequency (f1); and a power receiving device which includes a secondary coil which induces a current on the basis of alternating magnetic fluxes from the primary coils. The operating frequency (f1) which excites the primary coils is set to either a resonant frequency (fb2) or near thereto (fx-fy) of a resonance assembly which is formed when the secondary coil is present in a staggered location between two adjacent primary coils.
