The multiple power supply coils comprise one main coil and two auxiliary coils. Each auxiliary coil has a width that is less than half the width of the main coil, and a length that is equal to the length of the main coil. Each auxiliary coil is arranged to overlap on the main coil. The direction of the current flowing through the main coil and the auxiliary coil is controlled according to the amount of deflection of a current-collecting coil with respect to the power supply coil. Multiple power supply coils can be used for wireless charging of electric vehicles and industrial equipment. Les multiples bobines d'alimentation électrique comprennent une bobine principale et deux bobines auxiliaires. Chaque bobine auxiliaire a une largeur qui est inférieure à la moitié de la largeur de la bobine principale, et une longueur qui est égale à la longueur de la bobine principale. Chaque bobine auxiliaire est agencée pour chevaucher la bobine principale. La direction du courant circulant à travers la bobine principale et la bobine auxiliaire est commandée en fonction de la quantité de déviation d'une bobine de collecte de courant par rapport à la bobine d'alimentation électrique. De multiples bobines d'alimentation électrique peuvent être utilisées pour une charge sans fil de véhicules électriques et d'équipements industriels. 다중 급전코일은 1개의 주 코일과 2개의 보조코일을 포함한다. 각 보조코일은 폭이 상기 주 코일의 폭의 절반보다 작으며, 길이가 상기 주 코일의 길이와 동일하다. 각 보조코일은 주 코일과 중첩하도록 배치된다. 집전코일이 급전코일에 대하여 편향되는 정도에 따라, 주 코일과 보조코일에 흐르는 전류의 방향을 제어한다. 다중 급전코일은 전기 자동차 및 산업용 장비의 무선충전을 위하여 이용될 수 있다.
