Abstract:
1. A non-contact power feeder for supplying power by electromagnetic induction from a primary winding driven by an AC power supply to a secondary winding disposed with an air gap between the primary winding, further comprising: a series capacitor connected in series with one of the primary winding and the secondary winding and a parallel capacitor connected in parallel with the other one of the primary winding and the secondary winding; and the capacitance value Cp of the parallel capacitor converted to the primary side is set to: and the capacitance value Cs of the series capacitor converted to the primary side is set to: where, f 0 is the frequency of the AC power supply, x 1 is the primary leakage reactance at the frequency F 0 of the transformer comprising the primary winding and the secondary winding, x 2 is the secondary leakage reactance converted to the primary side, x 0 is the excitation reactance and X is x 1 in case of connecting the parallel capacitor in parallel with the primary winding or x 2 in case of connecting in parallel with the secondary winding.
