Abstract
A wireless power transmission apparatus according to various embodiments of the present invention may comprise: a power provision circuit for providing direct current (DC) power; a first conductive pattern; a second conductive pattern; multiple first switches connected to one end of the first conductive pattern and one end of the second conductive pattern; multiple second switches connected to the other end of the first conductive pattern; multiple third switches connected to the other end of the second conductive pattern; and a control circuit, wherein the control circuit controls the multiple first switches and the multiple second switches to convert the DC power into first alternating current (AC) power and apply the first AC power to the first conductive pattern and control the multiple first switches and the multiple third switches to convert the DC power into second AC power and apply the second AC power to the second conductive pattern. Various other embodiments are possible.
