Non-contact power transmission apparatus
TL;DR: In this paper, a non-contact power transmission apparatus with an AC power source and a resonance system is described. But the primary side resonance coil is separated from the primary coil in an axial direction by a first distance, and the secondary coil from the secondary side resonance coils in the axial directions by a second distance, at least one of the first distance is adjusted to be a distance that is determined in advance in accordance with the impedance of the load so that the power transmission efficiency is maintained at a proper value.
