A multiple power supply coil includes one main coil and two auxiliary coils. Each auxiliary coil has a width less than half a width of a main coil and a length equal to a length of the main coil. Each auxiliary coil is arranged to overlap the main coil. Depending on a degree to which a current collecting coil is deflected with respect to a power supply coil, directions of currents flowing in the main coil and the auxiliary coil are controlled. The multiple power supply coil can be used for wireless charging of an electric vehicles and industrial equipment. 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.
