Advanced Energy Industries just dropped a product that speaks directly to one of the most consequential bottlenecks in modern computing: keeping the lights on. The company’s new ADH series of DC-DC converters is purpose-built for the 800 V DC power architectures that next-generation AI data centers are rapidly adopting, capable of stepping down 800 V DC to 50 V DC with a peak efficiency of 98.2%.

What Advanced Energy actually built

The ADH series converters are half-brick form factor units that deliver peak power output of up to 8 kW and a full load capacity of 6 kW. They operate at multi-MHz switching frequencies, which is the technical way of saying they can handle rapid power demands without choking.

Power density exceeds 2,700 watts per cubic inch at peak and 2,000 watts per cubic inch under full load.

That 98.2% peak efficiency number is the headline stat. For every 100 watts of electricity flowing through the converter, only 1.8 watts gets lost as heat. Traditional AC-based power distribution systems in data centers can lose significantly more than that across multiple conversion stages.
