Advanced Energy Industries Launches The ADH Series Of DC-DC Converters For Next Generation 800 V DC AI Data Center Power Architecture

With best-in-class high power density and efficiency, these converters are designed to enable the industry transition to megawatt rack power.

The ADH series converts 800 V DC input into 50 V DC output, operating at multi-MHz switching frequency with a peak power efficiency of 98.2%. The converters deliver up to 8 kW peak power and 6 kW full load power in a standard half-brick package, delivering peak power density of over 2,700 W/In3 and full load power density of over 2,000 W/In3.

"The data center industry's shift to 800 V DC power architecture requires a new wave of innovation to deliver highly optimized power for next-generation AI servers," said David Richmond, Advanced Energy's senior vice president of high-volume products. "Working in close collaboration with several leading customers, we have developed and delivered samples of the ADH converters and plan to expand the portfolio with additional power levels and form factors. Advanced Energy is advancing a comprehensive portfolio of 800 V DC power conversion solutions designed to meet the critical demands of this emerging power paradigm."

The new ADH series is designed to leverage advanced liquid-cooled baseplates for optimized thermal management. Its standard form factor and its ability to connect modules in parallel enable significant power scaling. The ADH series design also includes the safety critical insulation required for systems operating at hazardous input voltage levels.

By combining the ADH series with the NDQ series of ultra-efficient 50 V DC to 12 V DC non-isolated bus converter (NIBC) and the newly developed Hot Swap Control (HSC) module, which manages inrush current and provides additional protection functions, Advanced Energy delivers complete 800 V DC power solutions that enable higher power levels and the increased power density required for megawatt-capable AI server racks.
