Abstract
A non-contact power transmission apparatus is disclosed. The non-contact power transmission apparatus includes an AC power source, a primary coil, a primary side resonance coil, a secondary side resonance coil, a secondary coil, a voltage measuring section, and a distance calculating section. AC voltage of the AC power source is applied to the primary coil. A load is connected to the secondary coil. The voltage measuring section measures the voltage of the primary coil. The distance calculating section calculates the distance between the primary side resonance coil and the secondary side resonance coil based on the voltage measured by the voltage measuring section.
