PROBLEM TO BE SOLVED: To provide a non-contact power feeding apparatus preventing the breakdown of a switching element or the like due to the generation of an overcurrent in an abnormal case such as non-connection of a track (induction path) by limiting AC-current through an AC-current limiting element in case of power supply.SOLUTION: The non-contact power feeding apparatus is constituted of a power feeding device 12 and a power feeding unit 13. The power feeding device 12 is composed of an insulating transformer 24 consisting of a primary coil 22 with a center tap 22a supplied with a DC current, a secondary coil 23 connected to the power feeding unit 13 and a tertiary coil connected to a relay 18 for short-circuiting a capacitor 16. The power feeding device 12 is further composed of a resonance capacitor 25 connected in parallel with the secondary coil 23 of the insulating transformer 24, and a first transistor 33 and a second transistor 34 connected to one end 22b and the other end 22c of the primary coil 22 respectively. |
