Abstract

In this paper, we developed a bidirectional LDC(Low DC-DC converter) for vehicle which is composed of a full bridge converter and a current doubler at the second side. The LDC is a converter that converts DC input from one side to DC output on the other side, and the converter which was developed in this thesis is capable of transferring power in both directions. It has been verified that the developed LDC has 90% efficiency at 1400W and approximately 85% efficiency at 2KW.

본 논문에서 풀브리지 컨버터와 2차측은 전류더블러로 구성되어 있는 차량용 양방향 LDC를 개발하였다. LDC는 한쪽의 DC입력을 다른쪽의 DC 출력으로 변환시키는 컨버터이며, 본 논문에서 개발된 컨버터는 양방향으로 전력전달이 가능하다. 개발된 LDC는 1400W에서 90%의 효율을 보이고 2KW에서 약 85%정도의 효율을 나타내는 것이 확인되었다.
