Abstract
(EN) The present invention relates to a power feeding and current collecting system for wireless charging and, more specifically, to a power feeding and current collecting system for on-road wireless charging of an electric vehicle, such as an electric bus, electric car, tram, light rail vehicle and subway, and an industrial machine comprising a rubber tyred gantry crane (RTGC). According to the present invention, by resolving the problem of internal pressure on an existing power feeding line by means of a capacitor provided in "an inverter" or "a box" positioned outside the road and a power feeding line design and a common line placement design, an on-road wireless power feeding line can be expanded, and the economic efficiency of the wireless charging system is greatly enhanced due to such expandability. Provided is a power feeding system for wireless charging which sufficiently satisfies such compatibility at a lower cost. The magnetic field offsetting effect is maximized by means of the structure of the common line and a shielding pipe, and thus the electromagnetic interference (EMI) of the power feeding line is reduced.
(FR) La présente invention concerne un système d'alimentation électrique et de collecte de courant pour une charge sans fil et, plus spécifiquement, un système d'alimentation électrique et de collecte de courant pour la charge sans fil sur route d'un véhicule électrique, tel qu'un bus électrique, une voiture électrique, un tramway, un véhicule ferroviaire léger et un métro, ainsi qu'une machine industrielle comprenant une grue à portique à pneumatiques en caoutchouc (RTGC). Selon la présente invention, en résolvant le problème de pression interne sur une ligne d'alimentation électrique existante au moyen d'un condensateur fourni dans « un onduleur » ou « une boîte » positionné(e) à l'extérieur de la route et une conception de ligne d'alimentation électrique et une conception de placement de ligne commune, une ligne d'alimentation électrique sans fil sur route peut être étendue et l'efficacité économique du système de charge sans fil est considérablement améliorée en raison de cette extensibilité. L'invention concerne un système d'alimentation électrique pour charge sans fil qui satisfait de manière suffisante une telle compatibilité à un coût inférieur. L'effet de décalage de champ magnétique est maximisé au moyen de la structure de la ligne commune et d'un tuyau de blindage, et ainsi l'interférence électromagnétique (EMI) de la ligne d'alimentation électrique est réduite.
(KO) 본 발명은 무선충전 급전 및 집전 시스템에 관한 것으로서, 더욱 상세하게는 전기 버스, 전기 승용차, 트램, 경전철, 지하철 등의 전기차량 및 RTGC(Rubber Tyred Gantry Crane)를 포함한 산업용 장비의 운행 중 무선충전 급전 및 집전 시스템에 관한 것이다. 본 발명에 의하면, 종래 급전선로 상의 내압 문제를 도로 밖에 존재하는 '함' 또는 '인버터'에 구비된 캐패시터와, 급전선로 설계 방안 및 공통선 배치 설계로 해결함으로써 주행중 무선 급전선로의 확장을 가능하게 하며, 이러한 확장성에 따라 무선 충전 시스템의 경제성 문제를 크게 개선한다. 더욱 저렴한 비용으로 그와 같은 호환성을 충분히 만족시키는 무선 충전 급전 시스템을 제공하며, 나아가, 공통선의 구조 및 차폐관을 이용하여 자기장 상쇄 효과를 극대화함으로써 급전선로의 EMI(ElectroMagnetic Interference)를 저감시킨다.
