Abstract
A contactless power supply system includes: a power transmitter including a first capacitor and a power transmission coil, and having a first resonant frequency; a power receiver including a second capacitor and a power reception coil, and having a second resonant frequency; and a repeater that transmits, to the power reception coil, AC power received from the power transmission coil. The repeater may include: a relay power reception coil unit that receives AC power and includes at least one coil that defines a first stray capacitance for forming a first self-resonant frequency having a frequency identical to the first resonant frequency; and a relay power transmission coil unit that transmits AC power and includes at least one coil that defines a second stray capacitance for forming a second self-resonant frequency having a frequency identical to the second resonant frequency.
