PROBLEM TO BE SOLVED: To reduce a leakage magnetic field emitted in non-contact power transmission, without separately providing a device for cancelling the leakage magnetic field.SOLUTION: A non-contact power supply system comprises operation setting means for performing setting on AC current to be supplied to power transmission coils of n (n is an integer of 2 or more) power supply devices. The setting is performed so that frequencies of the AC current are the substantially same and phases of the AC current are shifted in order by substantially (360/n) degrees when the n power supply devices perform power transmission. |
