PROBLEM TO BE SOLVED: To provide a non-contact power feeding device and a method of controlling the same, capable of preventing increase in size while suppressing radiation electric field intensity.SOLUTION: In a non-contact power feeding device 1, a power is transmitted or received in a non-contact manner between a power feeding side circuit 10 having a first coil L1 and a power reception side circuit 20 having a second coil L2 at least by magnetic coupling, and a magnetic pole direction of the first coil L1 becomes opposite to that of the second coil L2 at power transmission and reception. The power feeding side circuit 10 comprises a power controller 15 driving an inverter 14 to generate a high-frequency power to be supplied to the first coil L1. The power controller 15 selects a frequency lower than a resonance frequency of the power reception side circuit 20 and within a range where a composite ampere turn of the first coil L1 and the second coil L2 becomes smaller than the composite ampere turn at a resonance frequency of the power reception side circuit 20, and then, drives the inverter 14. |
