New DC-DC Converters deliver best-in-class peak power efficiency and density
Advanced Energy Industries, Inc. (Nasdaq: AEIS), a global leader in highly engineered, precision power conversion, measurement and control solutions,today announced the ADH series of DC-DC converters designed fornext generation 800VDC AI data center power architecture. With best-in-class high power density andefficiency, these converters are designed to enable the industry transition to megawatt rack power.
The ADH seriesconverts800VDC input into 50 VDC output,operating at multi-MHz switching frequency with a peak power efficiency of 98.2%.The convertersdeliver 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 800VDC 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 deliveredsamples of the ADH convertersand plan to expand the portfolio with additional power levels and form factors. Advanced Energy is advancing a comprehensive portfolio of800VDCpower conversion solutions designed to meet the critical demands of this emerging power paradigm.”
The new ADH series is designed to leverage advanced liquid-cooled baseplatesfor optimized thermal management. Its standard formfactorand its ability to connect modules in parallel enable significant power scaling.The ADH series designalso 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 VDC to 12 VDC 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 800VDC power solutionsthat enablehigher power levels and the increased power density required for megawatt-capable AI server racks.
