Title:
Non-contact electric supply transformer
Document Type and Number:
Japanese Patent JP6147741
Kind Code:
B2
Abstract:
At least one of a power transmission coil (10) and a power reception coil (20) is configured by a coupled and both-sides wound coil that is configured by combining a plurality of single both-sides wound coils (100, 200). For the single both-sides wound coils (100, 200), a single both-sides wound coil having a state in which a leakage magnetic flux around a moving body of when two single both-sides wound coils are installed at an install position of the moving body does not exceed a predetermined value is selected. Then, a number of the single both-sides wound coils combined to configure the coupled and both-sides wound coil is set so that a value obtained by multiplying the power transfer capacity of the single both-sides wound coil by the number satisfies the power transfer capacity of the contactless power transfer transformer. The leakage magnetic flux can be reduced, and increase in capacity can easily be realized by the number of combination.
