More Information
Summary:A non-contact power supply system includes a power supply device and a power reception device. The power supply device includes primary coils arranged on a power supply surface and configured to be excited at an operational frequency. The power reception device includes a secondary coil configured to induce current using resonance phenomenon based on alternating flux from the primary coils when arranged on the power supply surface. The operational frequency that excites the primary coil is set at or in the proximity of a resonance frequency of a resonance system formed when the secondary coil is located at an intermediate position between two of the primary coils that are adjacent to each other.
