Overview
Infineon introduced an 18 kW three-phase server power-supply reference design as part of two high-efficiency solutions for next-generation AI data center architectures. The design is engineered for high power density and improved thermal performance, with efficiencies quoted up to 99%.
It leverages Infineon's silicon, silicon-carbide and gallium-nitride technologies, reflecting the industry's move toward higher per-shelf power and the 800 VDC distribution architectures planned for AI racks. Reference designs like this let server and power-shelf designers evaluate the topology before productization.
Key Benefits
18 kW per reference design · three-phase AC input · up to 99% efficiency · Si + SiC + GaN technologies · targets AI data center power architectures.
Applications
AI and hyperscale data center power shelves, server PSU development, 800 VDC power architecture evaluation, and high-efficiency three-phase AC-DC design.
