Summary:A DC-DC converter is disclosed. The DC-DC converter comprises: a clamp unit connected to the input side through an inductor and including a plurality of clamp switches connected in parallel with each other and a clamp capacitor connected to the plurality of clamp switches; a first switching unit connected in parallel with the clamp unit and including first and third switches connected in series; a second switching unit connected in parallel with the clamp unit and including second and fourth switches connected in series; a first transformer connected to a second intermediate node of the first and third switches and a first intermediate node between the plurality of clamp switches and the clamp capacitor; a second transformer connected to a third intermediate node and the first intermediate node of the second and fourth switches; and a rectifier circuit which rectifies and outputs the output power of the first transformer and the second transformer. Accordingly, the present invention can implement a highly efficient DC-DC converter for a fuel cell with low voltage and high current characteristics. DC-DC 컨버터가 개시된다. 본 DC-DC 컨버터는 인덕터를 통해 입력 측과 연결되며, 서로 병렬로 연결된 복수의 클램프 스위치 및 복수의 클램프 스위치에 연결된 클램프 커패시터를 포함하는 클램프부, 클램프부와 병렬로 연결되며, 직렬 연결된 제1 및 제3 스위치를 포함하는 제1 스위칭부, 클램프부와 병렬로 연결되며, 직렬 연결된 제2 및 제4 스위치를 포함하는 제2 스위칭부, 제1 및 제3 스위치의 제2 중간 노드와 복수의 클램프 스위치와 클램프 커패시터 사이의 제1 중간 노드에 연결되는 제1 변압기, 제2 및 제4 스위치의 제3 중간 노드와 제1 중간 노드에 연결되는 제2 변압기, 및 제1 변압기 및 제2 변압기의 출력 전원을 정류하여 출력하는 정류 회로를 포함한다.
