WIRELESS CHARGING SYSTEM FOR ELECTRIC VEHICLE
The present invention relates to a wireless charging system which charges an electric vehicle and the like by using a capacitive wireless power transmission method. One aspect of the present invention is a wireless charging transmitting unit which provides electric power wirelessly through capacitive coupling with a receiving unit including at least two receiving unit conductive plates, and comprises: a pad unit which is capacitively coupled with the receiving unit conductive plate and includes larger numbers of conductive plates compared to the number of the receiving unit conductive plates; and a switching circuit which selectively connects each of the conductive plates with a direct current power supply. The present invention aims to reduce misalignment between the conductive plates of the transmitting unit and the conductive plates of the receiving units.
본 발명은 용량성 무선 전력 전송 방식을 사용하여 전기 자동차 등을 충전하는 무선 충전 시스템에 관한 것이다. 본 발명의 일 측면은, 적어도 두 개의 수신부 도체판을 포함하는 수신부에 정전용량 결합을 통해 무선으로 전력을 제공하는 무선 충전 송신부로서, 상기 수신부 도체판과 정전용량 결합(capacitively coupled)되는, 상기 수신부 도체판의 개수보다 많은 수의 도체판를 포함하는 패드부; 및 상기 도체판의 각각을 직류 전원과 선택적으로 연결하는 스위칭 회로;를 포함하는 무선 충전 송신부이다.
