The present invention proposes a wireless power transmitter and a wireless power receiver with improved structures. The wireless power transmitter comprises: a plurality of wires; a power supply connected to one end of the wires; and switches connected to the other end of the wires, wherein currents of the same or different values flow through each of the wires depending on the voltage applied to the switches, such that a magnetic field is generated outside the wires. In addition, the wireless power receiver comprises: a receiving coil that picks up the magnetic field generated by the transmitter; and a load connected to the receiving coil. The wireless power receiver may further comprise a magnetic body within the receiving coil, and the magnetic body may be manufactured in various shapes such as a hexahedron and a cylindrical shape.

    La présente invention concerne un émetteur d'énergie sans fil et un récepteur d'énergie sans fil présentant des structures améliorées. L'émetteur d'énergie sans fil comprend : une pluralité de fils ; une alimentation électrique connectée à une extrémité des fils ; et des commutateurs connectés à l'autre extrémité des fils, des courants de valeur identique ou différente s'écoulant à travers chacun des fils en fonction de la tension appliquée aux commutateurs, de telle sorte qu'un champ magnétique est généré à l'extérieur des fils. En outre, le récepteur d'énergie sans fil comprend : une bobine de réception qui capte le champ magnétique généré par l'émetteur ; et une charge connectée à la bobine de réception. Le récepteur d'énergie sans fil peut en outre comprendre un corps magnétique à l'intérieur de la bobine de réception, et le corps magnétique peut être fabriqué sous diverses formes telles qu'un hexaèdre et une forme cylindrique.

    본 발명은 구조가 개선된 무선전력 송신기 및 무선전력 수신기를 제안한다. 무선전력 송신기는, 복수 개의 전선; 상기 전선들의 일 단에 연결된 전원장치; 상기 전선들의 타 단에 연결된 스위치들을 포함하고, 상기 스위치에 인가되는 전압에 따라 상기 각 전선에는 서로 동일하거나 다른 값의 전류가 흐르면서 상기 전선들의 외측에 자기장이 생성되도록 한다. 그리고 무선전력 수신기는, 상기 송신기에서 생성된 자기장을 픽업하는 수신 코일; 및 상기 수신 코일에 연결되는 부하를 포함하여 구성된다. 수신기에는 수신 코일 내에 자성체가 더 구비될 수 있고, 자성체는 육면체 및 원통형상 등 다양한 형상으로 제작할 수 있다.
