COIL UNIT USED FOR NON-CONTACT POWER SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a coil unit used for a non-contact power supply system capable of minimizing the loss due to the power supply while maximizing the power transmission efficiency.SOLUTION: The non-contact power supply system transmits the power between a power supply device 2 and a power reception device 3. The power supply device 2 includes an electromagnetic field regulation part 14 which is formed of a material of high magnetic permeability or low resistance and is electrically connected to an antimagnetic plate 13 disposed outside of the periphery of a power transmission coil 11. The power transmission coil 11 provided to the power supply device regulates the distribution region of the generated electromagnetic field.
