인피니언, AI 데이터센터 및 서버용 12kW 고밀도 전원공급장치 레퍼런스 디자인 출시
Press Release
2025년 9월 17일, 서울 – 인피니언 테크놀로지스(코리아 대표이사 이승수)는 AI 데이터센터 및 서버 애플리케이션을 위해 특별히 설계된 고성능 전원공급장치(PSU) 용 12kW 레퍼런스 디자인을 출시했다. 높은 효율과 높은 전력 밀도를 제공하며, 실리콘(Si), 실리콘 카바이드(SiC), 갈륨 나이트라이드(GaN) 등 모든 반도체 소재를 활용한 레퍼런스 디자인은 연구개발 엔지니어, 하드웨어 설계자, 전력 전자 시스템 개발자를 위한 것이다.
인피니언 파워 스위치 부문의 리차드 쿤칙(Richard Kuncic) 수석 부사장은 "인공지능의 증가하는 에너지 수요에 대응하여, 인피니언은 가능한 모든 와트를 보존하기 위해 최고 수준의 변환 효율을 갖춘 전력 솔루션을 제공하는 데 기여하고 있다. 인피니언의 새로운 12kW 고밀도 PSU 레퍼런스 디자인은 첨단 전력 변환 토폴로지 및 CoolMOS™, CoolSiC™, CoolGaN™을 활용하여 PSU가 에너지 효율, 신뢰성, 전력 밀도의 잠재력을 최대한 발휘할 수 있도록 한다.”라고 말했다.
이 디자인은 고성능을 달성하기 위해 AC/DC 및 DC/DC 전력단 모두에서 첨단 전력 변환 토폴로지를 활용한다. 프런트엔드 AC/DC 컨버터는 3레벨 플라잉 커패시터 인터리브 역률 보정(PFC) 토폴로지를 특징으로 하며, 99.0퍼센트 이상의 피크 효율을 달성하는 동시에 자성 부품의 크기를 줄인다. 이는 높은 스위칭 성능과 탁월한 열 특성을 제공하는 인피니언의 CoolSiC 기술을 통해 달성된다. 절연형 DC/DC 컨버터는 풀 브리지 LLC 공진 컨버터를 특징으로 하며, 두 개의 플래너 트랜스포머와 인피니언의 CoolGaN 기술을 사용하여 98.5퍼센트 이상의 피크 효율을 제공한다. 이러한 아키텍처는 인피니언의 최신 와이드 밴드갭 기술과 결합되어 최대 113W/in³의 전력 밀도를 달성한다.
12kW PSU 레퍼런스 디자인의 또 다른 핵심 기능은 전체 전원 공급 토폴로지에 통합된 양방향 에너지 버퍼이다. 이 컨버터는 홀드업 시간 요건을 충족하는 동시에 정전용량 요건을 크게 줄인다. 또한, 에너지 버퍼는 그리드 형성 기능을 제공하여 시스템 신뢰성을 향상시키고 과도현상 발생 시 그리드에서 끌어오는 전력의 변동 및 변화율을 제한한다.
