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.
