인피니언, 효율과 유지보수 편의성을 강화하는 최첨단 800V AI 데이터센터 전력 아키텍처 개발
인피니언, 효율과 유지보수 편의성을 강화하는 최첨단 800V AI 데이터센터 전력 아키텍처 개발
Press Release
2025년 10월 21일, 서울 – 인피니언 테크놀로지스(코리아 대표이사 이승수)는 엔비디아가 컴퓨텍스 2025에서 발표한 AI 인프라용 800V 직류(VDC) 전력 아키텍처를 지원한다. 인공지능의 기하급수적인 성장은 현재의 54V 데이터센터 전력 인프라의 용량을 빠르게 초과하고 있다. 중앙 집중식 800VDC 아키텍처로 전환하면 전력 손실 감소, 효율성과 신뢰성 향상이 가능하다. 그러나 새로운 아키텍처는 잠재적 위험과 유지 보수로 인한 서버 다운타임 등의 손실을 방지하기 위해 새로운 전력 변환 솔루션과 안전 메커니즘을 필요로 한다.
인피니언 전력 및 센서 시스템 사업부의 아담 화이트(Adam White) 사장은 "전력 없이는 AI도 없다. 인피니언은 미래 AI 데이터센터의 전력 수요를 충족하는 동시에 시스템 다운타임을 최소화하는 서비스가 용이한 아키텍처를 제공하기 위해 엔비디아와 함께 지능형 전력 시스템을 개발하고 있다. 고밀도이며 신뢰성과 안전성을 갖춘 800V 전력 데이터 센터로의 전환을 주도함으로써 인피니언은 AI 서버 랙에 전력을 공급하는 방식을 혁신하고 있다. 인피니언의 비전은 모든 와트의 가치를 극대화하여 궁극적으로 더 효율적이고 지속 가능한 AI 생태계의 길을 여는 것이다.”라고 말했다.
AI 데이터 센터 운영자들은 인공지능을 위한 고성능 컴퓨팅에 막대한 투자를 하고 있으며, 스타게이트(Stargate)와 같은 프로젝트에는 수십억 달러에 달하는 막대한 자본 지출 (CAPEX)이 요구된다. 높은 투자 수익률을 보장하려면 AI 서버 랙의 가동 시간을 극대화하는 것이 매우 중요하며, 이를 위해서는 서비스가 용이한 모듈식 확장형 구성이 필수적이다. 인피니언과 엔비디아는 향후 서버 보드가 800VDC 전원 아키텍처에서 동작할 수 있도록 하는 핫스왑 컨트롤러 기능 등 안전성과 서비스 관련 측면에서 협력하고 있다. 전체 랙이 작동하는 동안 800VDC 버스에서 서버 보드를 교체하려면 보드의 사전 충전 및 방전을 제어해야 한다. 인피니언은 첨단 반도체 소재인 실리콘 카바이드(SiC) 기반 전용 솔루션으로 이를 지원한다. CoolSiC™ JFET 기술을 통해 데이터 센터 운영자는 다른 서버가 동일한 랙에서 계속 작동하는 동안 800VDC 아키텍처에서 서버 보드를 교체할 수 있다. 이는 다운타임 위험을 줄이고 서버 랙의 안전한 유지 관리를 가능하게 한다.
800V 직류 아키텍처 (VDC)로의 전환은 미래의 강력한 AI 기가팩토리 구축을 위한 중요한 진전이다. AI 서버 랙의 전력 소비는 약 120kW에서 500kW이며, 2020년대 말에는 1MW까지 증가할 것으로 예상된다. 이미 발표한 바와 같이, 인피니언은 엔비디아와 협력하여 800VDC로 구동되는 가속 컴퓨팅 플랫폼을 위한 첨단 전력 변환 솔루션을 개발할 예정이다. 인피니언은 자사의 중간 버스 컨버터 (IBC) 기술과 질화갈륨 (GaN) 기반 고주파 스위칭 솔루션을 활용하여 전력망에서 서버 코어까지 3단 및 2단 변환 솔루션 개발을 가속화하고 있다. 두 가지 접근 방식 모두 변환 단계 당 최대 98퍼센트의 효율을 달성하여 데이터 센터 운영자에게 가장 적합한 솔루션을 제공하는 것을 목표로 한다.
AI 서버 비용은 기존 서버보다 최대 30배 높기 때문에 전력 손실을 줄이고 높은 서비스 가동 시간을 보장하는 것이 AI 데이터 센터의 총소유비용 (TCO)을 절감하고 탄소 발자국을 최소화하는 핵심 요소이다. 따라서 인피니언은 메가와트급 AI 서버 랙의 효율적이고 안전하며 지속 가능한 운영을 가능하게 하기 위해 핫스왑 컨트롤러, 신뢰성 높은 보호 기술, 모든 관련 반도체 소재를 기반으로 한 고효율 전력 변환 솔루션을 포함한 전체 시스템 솔루션을 제공하고 있다.

800VDC 전원 아키텍처에서 동작할 수 있도록 하는 핫스왑 컨트롤러 기능
인피니언의 CoolSiC™ JFET 기술을 통해 데이터 센터 운영자는 800 VDC 아키텍처에서 서버 보드를 교체할 수 있으며, 동일한 랙 내의 다른 서버들은 계속해서 작동할 수 있습니다.
