PROBLEM TO BE SOLVED: To prevent or lessen failures, e.g. disconnections of coils of damages of cores, from causing troubles in the operation of entire system by subdividing the coil to be wound around the core into a specified number or more of sections and connecting the subdivided coil sections. SOLUTION: When a power is fed to a feeder 2, an AC current is induced electromagnetically in the coil of each core 3 and full-wave is rectified through a rectifying circuit 5 to produce a DC current. An output current from the rectifying circuit 5 is passed through a smoothing capacitor 6, in order to suppress the ripples before being fed to a control power circuit 7. When the coils 4 wound around three or more cores 3 are connected in parallel, power of 67% of the maximum power supply capacity can be fed to a carrying vehicle 20 from remaining coils, even if power cannot be taken out from one of the plurality of coils 4 due to the disconnection of the coil 4, damage of the core 3, failure of a resonance capacitor 15, or the like.
