WIRELESS POWER SUPPLY SYSTEM AND WIRELESS POWER TRANSMISSION SYSTEM

摘要

[Problem] To provide a wireless power supply system and a wireless power transmission system such that a leakage magnetic field can be effectively reduced even when the relative position of a moving body with respect to a power-transmitting coil changes. [Solution] This wireless power supply system (St) has a travel lane (L) for wirelessly transmitting electric power to a moving body (V) and is provided with: a power-transmitting coil (Lt) that is arranged such that the axial direction of the coil is substantially parallel to the width direction of the travel lane (L); and electromagnetic shielding walls (P1, P2) that are arranged on both sides of the travel lane (L) along the direction in which the traveling lane (L) extends.
