Abstract
A contactless power supply system includes a first power transmission coil, a plug power reception coil, a plug power transmission coil, and a first power reception coil. The first power transmission coil and the plug power reception coil are configured to satisfy a relational equation of (L/L)=G/K=N/N, where Lrepresents a self-inductance of the first power transmission coil, Lrepresents a self-inductance of the plug power reception coil, Nrepresents a winding number of the first power transmission coil, Nrepresents a winding number of the plug power reception coil, Krepresents a coupling coefficient of the first power transmission coil and the plug power reception coil, and Grepresents a voltage conversion gain of the voltage applied to the plug power transmission coil relative to the voltage applied to the first power transmission coil.
