Abstract: 본 발명은 전기자동차의 운전및 에너지 회수장치에 관한 것으로서 전기자동차의 운전가능한 시간의 연장은 전기 자동차의 성능인 것이다. 이 문제는 배터리 성능의 향상, 모타의 효율개선 운전계통의 자동변속기등 기계적인 성능향상등으로 어느 정도의 운전시간 연장이 가능하겠으나 결정적인 방법은 소모된 전력의 효과적인 회생장치가 결국은 전기자동차의 운전시간 연장 즉 운전거리를 늘려주게되어 전기자동차 실용화 보급 화에 선진화기 된다고 보겠다. 이러한 이유로 전기자동차의 배터리 회생기술이 다양하게 연구 개발되어 실용화되고 있으나 아직은 결정적인 방법은 볼 수가 없으며 현실로는 복잡하고 고가인 하이브리드 방식만이 실용되고 있는 현실이다. 여기서 종래의 전력회생장치를 살펴보면 공전하는 모타의 기전력을 높이기 위하여 모타의 기전코일을 추가 권선 하기도 하고 회생회로의 승압장치도 설치하나  100-1000A 대의 대전류가 필요하여 고가의 설치비용이 필요하므로 전기자동차의 기본성능을 저해하는 역효과가 발생하게도 된다. 여기서 본 발명은 전기자동차에 전혀 새로운 운전장치와 전력회생장치를 사용하여 임의의 전력회생을 얻을 수 있으며 동시에 유연한 감속과 브레이크 작용을 할 수가 있게 되는 것이다.
