The PCIM Asia Shenzhen Summit was successfully held in Shenzhen recently. Suzhou Oriental Semiconductor Co., Ltd. participated in the exhibition with its full‑stack power solutions for computing servers, fully demonstrating its domestic capabilities for computing server power supply systems. The exhibits at the booth drew numerous industry‑chain customers, engineers and industry partners, who stopped by for in‑depth exchanges.

01  Keynote Speech: Three‑in‑One — A Systematic Interpretation of the Integrated Layout for Computing Power Supplies

At the concurrent Power Semiconductor Emerging Leaders Summit, Dr. Wang Yi, Director of the IC Technology Department at Oriental Semi, delivered a keynote speech. He systematically elaborated on the company’s strategic integrated‑product layout for computing‑server power supplies across three pillars: high‑performance power semiconductors, companion control ICs, and next‑generation high‑voltage DC bus protection.

At the power‑device level, Oriental Semi showcased its full portfolio of Super‑junction MOSFETs, SGT MOSFETs, SiC MOSFETs and GaN‑based products. The 4th‑generation SGT MOSFETs cater to high current‑density requirements in IBC and VRM applications. The new high‑frequency SiC MOSFETs are optimized for high‑power‑density PSU and DC‑DC applications. By optimizing device performance, they enable computing‑server power supplies to achieve higher power density and lower power loss.

Leveraging its controlling subsidiary Hynetek, Oriental Semi has closed the gap in digital control ICs, building a comprehensive digital IC portfolio spanning digital power controllers, industrial DSPs, gate drivers and analog operational amplifiers. Unlike the industry’s typical multi‑vendor fragmented approach, the in‑house manufacturer enables hardware‑software co‑optimization and delivers standardized reference designs, helping customers shorten R&D cycles and reduce BOM costs.

In response to the industry trend toward 800V high‑voltage DC buses, the company has introduced system protection solutions including high‑voltage hot‑swap and SSCB solid‑state circuit breakers. Paired with in‑house developed DSPs and control algorithms, these solutions deliver microsecond‑level fault protection, safeguarding the reliable operation of large‑scale computing‑power data center systems.

02  Exhibits Draw Strong Interest, Spirited On‑Site Exchanges

During the exhibition, Oriental Semi’s booth drew large crowds of professional visitors from server power supply, data center, new energy and industrial control sectors. The company showcased its complete integrated product portfolio spanning power devices, control ICs and system‑level solutions. Focusing on hot topics including full‑stack power solutions for computing‑server power supplies, 800V high‑voltage DC architecture protection and full‑link domestic substitution, the team held in‑depth technical discussions and requirement alignment with on‑site customers, partners and industry peers. Customers highly acknowledged Oriental Semi’s dual‑core synergy of “power devices + digital ICs”, and multiple power‑supply manufacturers expressed interest in further cooperation.

03  Future Development: White Paper Anchors a New Strategic Starting Point to Deepen Layout in the Core Computing Power Supply Track

Beyond the exhibition floor, the company has established a clear implementation roadmap for its business within the computing‑server power supply track. Oriental Semi recently released the 《White Paper on Computing‑Server Power Supply Systems》. Centered on its integrated “power devices + digital control ICs” capability, the white paper systematically breaks down the full‑chain product matrix covering PSU, IBC and VRM, as well as medium‑ and long‑term technology roadmaps. It serves not only as a technical handbook, but also as a strategic manifesto for its engagement in the computing‑power supply track.

Leveraging its full‑chain power supply architecture, Oriental Semi has realized end‑to‑end coverage spanning grid input all the way to computing chips. Its SiC and GaN devices are benchmarked against top global counterparts. Liquid‑cooling‑compatible power devices have achieved mass production and delivery. Digital power controllers have been adopted by leading global customers. Products are shipped in volume to customers including A, Honor, Megmeet, Vertiv and Delta, serving more than 2,000 end‑customers.

Moving forward, the company will further scale up R&D efforts based on the white paper as a new starting point, continue to deepen its layout in the core track of computing-server power supply systems, and empower the independent, controllable, efficient and low-carbon development of domestic computing power infrastructure.
