Document Type and Number:
WIPO Patent Application WO/2014/038148
Kind Code:
A1
Abstract:
The power transmission coil (10) of a power-supply device (1) and the power-receiving coil (20) of a power-receiving device (2) are configured so as to satisfy the formula (L2/L1)1/2=G/K, where L1 is the self-inductance of the power transmission coil (10), L2 is the self-inductance of the power-receiving coil (20), K is the coupling coefficient of the power transmission coil (10) and the power-receiving coil (20), and G is the voltage conversion gain of the secondary voltage output from the power-receiving coil (20) in relation to the primary voltage applied to the power transmission coil (10).
