무선 에너지 전송 시스템은 이물질 잔해 검출 시스템을 포함한다이 시스템은 진동하는 자기장을 생성하도록 구성되는 적어도 하나의 무선 에너지 전송 소스를 포함한다이물질 잔해는 진동하는 자기장 내에 위치된 적어도 하나의 자기장 구배측정기에 의하여 검출될 수도 있다적어도 하나의 자기장 구배측정기의 전압은 판독 회로부 및 피드백 루프를 사용하여 측정될 수도 있고 구배측정기로부터의 판독치는 무선 에너지 소스의 파라미터를 제어하기 위하여 사용될 수도 있다 A wireless energy transfer system includes a foreign object debris detection system. The system includes at least one wireless energy transfer source configured to generate an oscillating magnetic field. The foreign object debris may be detected by at least one field gradiometer positioned in the oscillating magnetic field. The voltage of the at least one field gradiometer may be measured using readout circuitry and a feedback loop based on the readings from the gradiometers may be used to control the parameters of the wireless energy source.
