  • Contactless power supply system
    Patent number: 9716386
    Abstract: In a contactless power supply system 10 having a secondary coil 13 receiving electric power generated from a primary coil 12 to be connected to a high-frequency power source 11, and a resonance coil 14 arranged in direct contact with the secondary coil 13 in between the primary coil 12 and the secondary coil 13, respective planarly-viewed areas of the secondary and the resonance coils 13, 14 are equal to or smaller than a planarly-viewed area of the primary coil 12, the primary coil 12 is formed by planarly and spirally winding a first litz wire 25, the resonance coil 14 is formed by tandemly winding coils 27, 28 in a double layer, the coils 27, 28 being formed by planarly and spirally winding a second litz wire 26, and the secondary coil 13 is formed by parallelly arranging and planarly and spirally winding third litz wires 29, 29a.
