INDUCTOR UNIT, WIRELESS POWER TRANSMISSION DEVICE, AND ELECTRIC VEHICLE

WIPO Patent Application WO/2015/189976

A1

[Problem] To provide: an inductor unit which has a plurality of inductors, and in which the coupling coefficient between the inductors is low; a wireless power transmission device; and an electric vehicle. [Solution] An inductor unit as in one embodiment of the present invention is provided with a first inductor and a second inductor. The first (second) inductor is provided with a first (second) core and a first (second) winding. The first (second) winding is wound around the periphery of the first (second) core. The first inductor and the second inductor are disposed so that the angle formed by a first straight line and a first center line is greater than 0° but less than 90°. The first straight line connects a first intersection and a second intersection. The first (second) intersection is an intersection between a first (third) center line that is parallel to a first (second) magnetic flux direction of the first (second) core, and a second (fourth) center line that is perpendicular to the first (second) magnetic flux direction.
