Non-contact power supply system and apparatus and carrying equipment using the system
First Claim
1. A non-contact power supply apparatus which interlinks a magnetic flux generated by an AC current flowing through a primary circuit with a secondary circuit so that an induced power is generated in the secondary circuit, and supplies a constant voltage to a load;
- wherein the secondary circuit includes;
a plurality of inductors connected in series; and
a plurality of capacitors each of which is interposed between said plurality of inductors;
wherein one capacitor of said plurality of capacitors and one inductor adjacent to said one capacitor have a substantially resonant relation with respect to a frequency of the AC current.

Abstract
In a non-contact power supply apparatus which interlinks a magnetic flux generated by an AC current flowing through a primary circuit with a secondary circuit so that an induced power is generated in the secondary circuit, and supplies a constant voltage to a load, the secondary circuit is composed of a plurality of inductors connected in series, and each of a plurality of capacitors is interposed between inductors. The total sum of inductance of the plurality of inductors and the total sum of capacitance of the plurality of capacitors have a resonant relation with respect to an AC current of the primary circuit.
