NON-CONTACT POWER SUPPLY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a non-contact power supply device comprising a simple configuration for securely restoring a power transmission winding unit to a reference position in a movable range of the power transmission winding unit.SOLUTION: A non-contact power supply device comprises: a platform P set on a road surface on which an electric vehicle can transit and stop; a power transmission winding unit 2 for exciting induced electromotive force and attractive force at a power reception winding unit 1 included in the electric vehicle; a support body F for making the power transmission winding unit 2 be capable of horizontally moving under the platform P; a magnetic base 3 for magnetically inducing the power transmission winding unit 2, in the central part under the support body F; a shield plate 4 lying between the power transmission winding unit 2 and the magnetic base 3; and operation frequency adjustment means for changing an operation frequency of the power transmission winding unit 2.SELECTED DRAWING: Figure 1
