Abstract:
This invention relates to a power transfer device via electromagnetic interaction. this invention proposes a power transfer device, comprising: a primary coil for transferring a power, including a first primary coil and a second primary coil; a secondary coil for transferring the power with the primary coil via electromagnetic interaction; wherein the secondary coil is positioned between the first primary coil and the second primary coil, the first and the second primary coil being configured to render the directions of the magnet fields they induce across the secondary coil consistent. With the specific association and positioning of the primary coil and the secondary coil, the power can be transferred between the primary coil and the secondary coil effectively; therefore, the size of the transfer device can be reduced significantly. This invention can be used for charging device, e.g. components of lighting products, electrical charging device, etc.
