800V Power Conversion Advances AI and High-Performance Computing

A new high-voltage DC-DC power conversion platform has been introduced that converts 800V DC input to 50V DC output, delivering up to 8kW peak power and 6kW continuous power. Designed specifically for AI and high-performance computing applications, it achieves a peak efficiency of 98.2% and offers exceptional power density exceeding 2,700 W/in³ at peak output.

Key Specifications

• Input voltage: 800V DC
• Output voltage: 50V DC
• Peak power: 8 kW
• Continuous power: 6 kW
• Peak efficiency: 98.2%
• Power density: > 2,700 W/in³ (peak), > 2,000 W/in³ (full load)
• Liquid-cooled design with parallel scaling capability

The platform is built in a standard half-brick form factor, enabling significantly higher compute density without increasing rack footprint. The combination of high voltage input, excellent efficiency, and extreme power density makes it an ideal solution for powering next-generation AI servers and accelerators.

Target Applications

• AI training and inference clusters
• High-performance computing (HPC) systems
• Advanced data center power architectures
• Next-generation GPU and accelerator racks

This 800V power conversion technology represents a major step forward in addressing the exploding power demands of modern AI infrastructure while improving overall system efficiency and thermal performance.
