Abstract
Provided is a contactless power transfer device for a moving object. Each of a power transmission coil and a power receiving coil comprises an H-shaped core, and first, second and third search coils are installed on a magnetic pole object of the H-shaped core of the power transmission coil. A y-direction positional deviation between the power transmission coil and the power receiving coil is detected using voltages measured at the first and second search coils, and an x-direction positional deviation is detected using voltages measured at the third search coils.
