MAGNETISM RESONANT COIL INCLUDING MULTIPLE LOOPS FOR MAGNETISM RESONANT WIRELESS POWER TRANSMISSION CAPABLE OF EFFECTIVELY TRANSFERRING WIRELESS POWER USING A MAGNETISM RESONANT COIL

摘要

PURPOSE: A magnetism resonant coil including multiple loops for magnetism resonant wireless power transmission is provided to promote the transmission distance and efficiency by obtaining high coupling state in a plurality of magnetism coupling areas. CONSTITUTION: A magnetism resonant wireless power transmission system including a magnetism resonant coil includes a transmission unit(Tx), A magnetism resonant coil(Cm1,Lm1,Lm2), and a reception unit(Rx). A relay magnetism resonant coil including multiple loops is provided between magnetism resonant coils including two single loops. A relay magnetism resonant coil includes the two loops for strong magnetism resonance between a transmission and a reception magnetism resonant coil. A reception unit includes the reception magnetism resonant coil and the relay magnetism resonant coil.
