Abstract
A non-contact power transmission apparatus having a resonance system is disclosed. The resonance system includes a primary coil to which an alternating-current voltage from an alternating-current source is applied, a primary-side resonance coil, a secondary-side resonance coil, and a secondary coil to which a load is connected. The impedance of the primary coil is set such that the output impedance of the alternating-current source and the input impedance of the resonance system are matched to each other.
