Abstract

A resonance system that receives power from a power source section is configured by at least a primary resonance coil, a secondary resonance coil, and a load. The output frequency fof the power source section is set to lie within one of the frequency ranges f≦f≦f, f≦f≦f, . . . , f≦f≦f. The frequencies f, f, f, f, . . . , f, f(f<f<f< . . . <f<f) are defined such that, if the input impedances of the resonant system at the time of supply of power of the frequencies f, f, f, f, . . . f, f(f<f<f< . . . <f<f) to the resonant system are represented by Z, Z, Z, . . . , Z, Z, the input impedances satisfy Z=Z, Z=Z, . . . , Z=Z.
