MAGNETIC-FIELD RESONANCE POWER TRANSMISSION DEVICE AND MAGNETIC-FIELD RESONANCE POWER RECEIVING DEVICE

摘要

Disclosed is a magnetic-field resonance wireless power transmission system wherein power is transmitted from a power transmission device to a power receiving device by means of magnetic field resonance and the efficiency of power transmission is improved. A magnetic-field resonance power transmission device (10) in a magnetic-field resonance wireless power transmission system (1) has: a resonance coil (11); a power supply unit (12) for supplying power to the resonance coil (11) and generating a magnetic field; a magnetic body (13) for altering the magnetic field generated by the resonance coil (11); and a position adjustment unit (14) for adjusting the positional relationship between the resonance coil (11) and the magnetic body (13).
