본 발명은 전자유도를 이용한 온라인 전기자동차의 자기장 통신장치에 관한 것으로, 보다 상세하게는 급전레일 위를 통과하는 차량 하부에 1차측 전자유도 회로부를 구성하여 직류(DC)전압을 교류(AC)전압으로 변환하고, 1차측 도선으로부터 지표면에 위치한 2차측 공진부하 회로부에 전자유도방식으로 에너지를 전달하여 인버터와 온라인 전기자동차의 통신이 가능한 전자유도를 이용한 온라인 전기자동차의 자기장 통신장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic field communication device for an online electric vehicle using electromagnetic induction. More particularly, a primary side electromagnetic induction circuit part is formed at a lower portion of a vehicle passing on a feed rail to convert a direct current (DC) voltage into an alternating current (AC) voltage.

최근 친환경적인 운송수단으로 전기자동차에 관한 관심이 폭발적으로 증가하고 있다. 전기자동차는 내연기관을 이용한 운송수단과는 달리 환경오염물질의 직접적인 배출이 없을 뿐 아니라, 이산화탄소 배출량, 소음, 진동을 크게 줄일 수 있는 장점을 가지고 있다. 동시에 전기자동차 구동의 원동력이 되는 전지가 중량, 크기, 비용 측면에서 큰 비중을 차지할 수밖에 없고 이를 주기적으로 충전해야 한다는 단점을 가지고 있다. 하지만, 온라인 전기자동차(On-Line Electric Vehicle, OLEV)는 급전도로 위를 주행하면서 전지를 충전하는 방식이므로 이러한 단점을 극복할 수 있다. 급전도로 위에 존재하는 유도 코일에서 자기장이 발생하고, 이를 이용해 주행 중이거나 정차 중인 온라인 전기자동차의 자체 전지를 충전함으로써 전기자동차에 장착되는 전지의 용량을 크게 줄이고, 별도의 충전시간 없이 장거리 전지 주행을 가능하게 한다. 그러나, 이동중이거나 정차중인 온라인 전기자동차에서 감지할 수 있는 위급 상황이 발생한 경우 급전레일을 차단할 수 없는 문제점이 있었다.Recently, interest in electric vehicles has exploded as an environmentally friendly vehicle. Unlike vehicles using internal combustion engines, electric vehicles have no direct emissions of environmental pollutants and have the advantage of greatly reducing carbon dioxide emissions, noise and vibration. At the same time, batteries, which are the driving force for driving electric vehicles, have to take up a large proportion in terms of weight, size, and cost, and have a disadvantage in that they are periodically charged. However, on-line electric vehicles (OLEVs) can overcome these drawbacks because they charge the battery while driving on a feed route. The magnetic field is generated from the induction coil on the power supply road, and by using this to charge the on-board electric vehicle's own battery while driving or stopping, it greatly reduces the capacity of the battery mounted on the electric vehicle and enables long-distance battery driving without additional charging time. Make it possible.
