A new generation of DC-DC power converters is designed to support the shift toward 800V data center architectures, delivering up to 8kW output power, high efficiency, and scalable deployment for next-generation AI infrastructure.
The race to build larger AI clusters is driving a major overhaul of data center power infrastructure, with 800V DC architectures emerging as a key enabler for future high-density computing environments. To address this transition, Advanced Energy Industries, Inc. has introduced a new DC-DC converter platform to help operators deliver power more efficiently to next-generation AI servers and megawatt-scale racks.
The converter is designed to step down 800V DC input to 50V DC output while operating at multi-megahertz switching frequencies. According to the manufacturer, the device achieves peak efficiency of 98.2%, helping reduce power losses and cooling requirements in increasingly power-hungry AI deployments.
The key features are:
- Converts 800V DC input to 50V DC output
- Delivers up to 8kW peak power and 6kW continuous power
- Achieves peak efficiency of 98.2%
- Power density exceeds 2,700W/in³ at peak output
- Liquid-cooled design with support for parallel power scaling
The platform delivers up to 8kW peak power and 6kW continuous full-load power within a standard half-brick form factor. This translates into power density exceeding 2,700W/in³ at peak output and more than 2,000W/in³ during full-load operation, addressing the industry’s demand for higher compute density without significantly increasing rack footprint.
Thermal management has also been a key focus of the design. The converter incorporates advanced liquid-cooled baseplates intended to improve heat dissipation in high-performance computing environments. Its standard footprint and support for parallel module operation allow system designers to scale power capacity as rack requirements increase.
The product also integrates insulation features required for systems operating at hazardous high-voltage input levels, an important consideration as data centers adopt higher-voltage power distribution schemes.
Beyond the converter itself, the platform is intended to work alongside complementary power management components, including 50V-to-12V bus conversion technology and hot-swap control modules. Together, these elements form a complete 800V power delivery ecosystem designed to support the growing power and density requirements of AI server infrastructure.
As AI workloads continue to push rack power consumption toward megawatt levels, solutions built around 800V DC architectures are expected to play an increasingly important role in improving efficiency, scalability, and overall data center performance.
