PROBLEM TO BE SOLVED: To provide a non-contact power supply system capable of simply switching the output of non-contact power supply to a constant voltage output or a constant current output.SOLUTION: In a SP system non-contact power supply transformer in which the value of a parallel capacitor 48 to be connected in parallel with a secondary coil 47 is set to cause resonate with the secondary coil, when the frequency of an AC power supply is f, and the value of a series capacitor 45 to be connected in series with a primary coil 46 is set so that the primary power supply power-factor becomes 1, frequency of the AC power supply is set to a frequency fdifferent from the f, at which the output from the transformer becomes a constant current output. In this SP system non-contact power supply transformer, the secondary output becomes constant voltage output when the frequency of the AC power supply is set to f, and becomes constant current output when the frequency is set to f. |
