Infineon Technologies and Delta Electronics are expanding their existing collaboration to develop advanced power modules with a vertical power supply for AI processors in hyperscale data centers. This should contribute to a significant reduction ofCO2 emissions in AI data centers.
The partnership is based on Infineon's silicon chip technology (MOSFET) and embedded packaging expertise as well as Delta's power module design and manufacturing capabilities. High-density modules with outstanding efficiency will be developed to enable a vertical power delivery (VPD) architecture for the xPUs in hyperscale data centers. Compared to a side-mounted, discrete solution, the use of vertical power supply modules can save up to 150 tons of CO₂ per rack over an expected lifespan of three years. Assuming that future hyperscale data centers will consist of up to 100 server racks, theamount of CO2 saved is equivalent to the emissions of around 4,000 households per year.
Delta uses Infineon's OptiMOS integrated 90A silicon-based power stage for the development of VPD modules. Vertical power supply is a key factor in improving system efficiency as it enables a more direct and compact power supply path. By supplying power vertically rather than horizontally, VPD modules reduce losses in the system's power supply network. As a result, the modules achieve higher power density and efficiency while reducing heat generation due to lower power losses. In addition, the vertical design creates additional space on the system board so that space in the data centers can be used more efficiently, enabling a more compact data center design.
The increasing demand for high-performance data centers for AI applications is growing exponentially. To meet this demand, data centers require power supply solutions that cover the growing energy requirements of AI applications. In addition, the increasing densification of IT racks, driven by the integration of tightly interconnected xPUs, requires the development of higher voltage power distribution solutions that can efficiently power these high-density systems. To address these challenges, Infineon and Delta are working together to develop next-generation power solutions for AI data centers, which will require 1 MW per rack in the future.
