Abstract
According to one embodiment, a repeater device for wireless power transfer having repeaters, measuring units and a control unit is provided. The repeaters supply electric power wirelessly and are placed in a plane substantially. Each of the repeaters has a repeater coil and a switch which enables disconnection of a current path of the repeater coil. The measuring units are provided for measuring respective power transfer efficiencies of the repeaters respectively. The control unit controls switching-on and switching-off of the switches of the repeaters based on a measuring result of the power transfer efficiencies obtained from the measuring units.
