Megawatt-Racks kommen: Wie 800-VDC-Architekturen Verluste reduzieren und Einschränkungen beseitigen
Flex-Leistungsmodule has introduced the BMR317, a third-generation, compact 8:1 fixed ratio intermediate bus converter engineered for next-generation AI data center and communication systems.
Built for space- and efficiency-constrained environments, the BMR317 is available in two variants delivering 800 W and 1,000 W of continuous power, with peak capabilities of up to 2,000 W and 2,500 W, respectively. This is designed to support robust performance for the fast, dynamic load steps typical of modern AI compute and inference workloads.
The open-frame design and linear component landscape enable optimized cooling capability and high-power density above 397 W/cm3 (9.1 kW/in3) for the 800 W variant. A hybrid switching capacitor (HSC) topology helps to further maximize efficiency and reduce EMI, making the BMR317 ideal for tightly packed accelerator cards, servers, and xPU platforms.
With a 40–60 V input range and a 5–7.5 V output (8:1 fixed ratio), along with PMBus management and compatibility with the Flex Power Designer-Tool, the BMR317 integrates seamlessly into advanced power architectures and complements downstream voltage regulator modules. This creates an efficient and scalable two-stage conversion path for high-current AI and hyperscale workloads. Compatible VRM solutions include Flex Power Modules’ BMR510 und BMR511 series of integrated power stages and Renesas’ RRV2x830 “Power Tower” series.
The 800 W variant of the BMR317 is available now, with the 1 kW variant scheduled for release in the second half of 2026.
