Abstract
Description
전기 자동차에 부착되는 충전 장치 중 절연형 컨버터를 이용하는 경우, 부피가 커지거나 효율이 저하되는 문제점이 있다.
도 2는 도 1의 전기 자동차를 구동하는 장치의 구성을 개략적으로 보인 도;
도 3은 일 실시 예에 따른 전기 자동차의 배터리 충전 장치의 구성을 개략적으로 보인 블록도;
도 4는 도 3의 배터리 충전 장치를 상세히 보인 회로도;
도 5a 및 도 5b는 도 3 또는 도 4의 2상 인터리브 컨버터의 동작을 설명하기 위한 도들; 및
도 6a 내지 도 6c는 도 3 또는 도 4의 비절연 2-스테이지 컨버터의 동작을 설명하기 위한 도들이다.
도 6b를 참조하면, 충전 장치 (300)는 승압 모드(부스트 모드)로 동작한다. 즉, 제2 스위칭 소자(S3)가 온/오프 스위칭하는 반면, 제1 스위칭 소자(S1)는 항상 턴-온된다. 이때, 제2 스위칭 소자(S3)가 턴-온 상태일 때, 전류 경로(M21)가 형성된다. 반면, 제2 스위칭 소자(S3)가 턴-오프 상태일 때, 전류 경로(M22)가 형성된다. 승압 모드의 경우, 비절연 2-스테이지 컨버터가 동작하는 영역으로서, 입력 전류가 연속적으로 흐르게 되므로, 최대 전력을 사용할 수 있다.
