PROBLEM TO BE SOLVED: To provide a non-contact power supply system which can appropriately supply power from each power reception unit to a load even if the specifications of each power transmission unit and each power reception unit and a coupling coefficient are different.SOLUTION: In a non-contact power supply system which supplies power from a power transmission device A to a power reception device B in a non-contact manner, the power transmission device A includes: a high frequency power supply device 4 which outputs a constant high frequency voltage; and power transmission units 11, 12, 13, and the power reception device B includes power reception units 21, 22, 23. The power transmission unit 11 (12, 13) includes a power transmission coil L11 (L12, L13). The power reception unit 21 (22, 23) includes a power reception coil L21 (L22, L23) magnetically coupled with the power transmission coil L11 (L12, L13). The output of each power reception unit 21, 22, 23 is connected in parallel. As a power transmission method from the power transmission unit 11 (12, 13) to the power reception unit 21 (22, 23), a magnetic field resonance method is applied.SELECTED DRAWING: Figure 2 |
