Kind Code:
A
Abstract:
To provide a non-contact power feed system capable of improving power feed efficiency by changing a power feed pattern to a primary coil.
The position and the attitude of a reception coil L3 are estimated based on a presence detection level of each power feed coil L1. At the position and the attitude, a power feed pattern that makes an output of a reception device 30 maximum is selected, and power feed is performed in the feed pattern. Thus, electric power can be supplied to the reception device 30 with high efficiency regardless of the position and the attitude of the reception coil L3.
