Title:
POWER COUPLER
Document Type and Number:
WIPO Patent Application WO/2009/010003
Kind Code:
A1
Abstract:
A power coupler includes base (14), housing (13), primary frame (1) and secondary frame (3). The primary coil (2) and secondary coil (4) are wound on the primary frame (1) and secondary frame (3) made of lower permeability magnetic medium respectively, and the frame portion wound by the secondary coil (4) is hollow in which the lower permeability magnetic medium (5) is set. The primary frame (1) is jacketed by lower permeability magnetic medium (5), the secondary coil (4) and the secondary frame (3) together. The lower permeability magnetic medium (5) is set in corresponding part between the outer portion of primary frame (1) and the inner portion of secondary frame (3), by which the lines of magnetic force in both the primary coil and secondary coil are close loop respectively. Therefore the flux variations in the primary coil and secondary coil are not affected mutually each other, the current generated by the secondary coil (4) inducted from the primary coil (2) is applied to the outside with high efficiency.
