전기차 주위의 다수의 무선통신기들 중에서 특정 그라운드 어셈블리의 무선통신기를 탐지하는 방법 및 장치와 그라운드 어셈블리의 작동 방법에 관한 것으로, 무선통신기 탐지 방법은, 충전 구역에 진입한 차량 주위의 무선통신기들을 검색하는 단계, 무선통신기들 각각의 복수의 수신 신호 세기들의 1차 평균치를 이용하여 무선통신기들 각각의 수신 신호 세기들을 필터링하는 단계, 필터링하는 단계에서 얻은 필터링된 수신 신호 세기의 개수로 1차 평균치에 가중치를 부여하여 1차 평균치를 정규화하는 단계, 및 정규화하는 단계에서 얻은 2차 평균치를 토대로 가장 강한 신호 세기값을 갖는 무선통신기와 연결을 시도하는 단계를 포함한다.

    An active rectifier for a wireless power transfer system includes: a first rectifying circuit; a second rectifying circuit; a first switching circuit and a second switching circuit. The first rectifying circuit, the second rectifying circuit, the first switching circuit, and the second switching circuit are arranged in a form of a bridge circuit between a secondary coil of a vehicle and a battery of the vehicle, and the active rectifier controls the first and second switching circuits according to a charging status of the battery or an output status of the wireless power transfer system in order to change or maintain a charging power to the battery.
