이 레퍼런스 디자인은 OCP Open Rack V3(ORV3) 규격 및 AI 서버 랙 아키텍처 요건을 충족하도록 설계됐으며, 제품 출시 기간 단축에 기여한다고 회사 측은 밝혔다.
480VAC 입력·50% 부하 조건에서 피크 효율 98% 이상을 달성하며, 5레벨 ANPC PFC 토폴로지와 3레벨 LLC 컨버터를 채용해 116W/in³의 전력 밀도를 구현한다고 밝혔다.
이는 ORV3 최소 요구사항인 94W/in³를 웃도는 수치다.
통합 에너지 버퍼는 전력망 장애 발생 시 20밀리초(ms)의 홀드업 타임을 제공하며, GPU 부하 급변 시 라인 전압을 안정화해 별도 커패시터 뱅크 유닛(CBU) 없이 운용 가능한 것으로 전해진다.
PSOC Control C3 Performance Line 마이크로컨트롤러에 내장된 프로그래머블 전력 제어 가속기(PPCA)가 빠른 동적 응답과 정밀한 전류·전압 제어를 담당한다.
입력 전압 범위는 311~528VAC 3상으로, 다양한 글로벌 전력망 규격에 대응한다고 회사 측은 설명했다.
대부분의 부하 동작 범위에서 입력 전류 총고조파왜율(iTHD)을 낮게 유지하고, 역률 0.99 이상과 -5°C~45°C 주변 온도 운용을 지원한다.
통합 플래너 마그네틱 구조를 통해 컴팩트하고 모듈화된 고주파 트랜스포머 설계도 지원한다.

Reducing '650V Over-Design'…400V SiC Targets Power Semiconductor Niche Market
Infineon's second-generation 400V and 440V class CoolSiC MOSFET reduces the 'over-design' that occurred when using existing 500-650V devices, enabling a light-fit design matched to actual required voltage. Optimization of cell pitch, channel, and drift region improved switching loss and conduction performance, with reduced on-resistance temperature dependency. Particularly in 3-level flying capacitor topology, efficiency improvement and inductor miniaturization effects are significant, with high efficiency demonstrated in PFC and buck converter testing. However, 3-level circuits require capacitor balancing and additional control and protection design, making the efficiency and power density advantages relative to overall cost the key to market expansion.

240W Era USB PD Charger: Design as a 'System,' Not Components
As USB-C PD expands to 240W, charger design has emerged as a necessity for system-level implementation rather than simple component combination. Topology must vary according to output—flyback, QR-ZVS, active clamp, and PFC+hybrid flyback configurations—and high-frequency design combining GaN (CoolGaN) and OptiMOS is required to achieve high power density. The PD controller handles not only communication but also power negotiation, protection, and multi-port power distribution, which determines system stability. Infineon presents reference designs scalable from 45W to 240W and emphasizes that high-output USB PD can secure competitiveness only through integrated optimization of cables, protection circuits, thermal management, and EMI.
