Advanced Energy Unveils Cutting-Edge 800 V DC Converters for AI Data Centers

In a significant advancement for the data center industry, Advanced Energy Industries, Inc. (Nasdaq: AEIS) has announced the launch of the ADH series of DC-DC converters, specifically engineered to support the burgeoning demand for 800 V DC power architecture in next-generation AI data centers. This innovative product is poised to revolutionize power conversion solutions, enabling the transition to megawatt rack power with unprecedented efficiency and density.

The ADH series is designed to convert an 800 V DC input into a 50 V DC output, operating at a multi-MHz switching frequency. Notably, the converters achieve a peak power efficiency of 98.2%, setting a new standard in the industry. The converters offer a remarkable peak power output of up to 8 kW and a full load power capacity of 6 kW, all within a standard half-brick package. This results in a peak power density exceeding 2,700 W/In³ and a full load power density surpassing 2,000 W/In³.

David Richmond, Senior Vice President of High-Volume Products at Advanced Energy, emphasized the importance of innovation in meeting the evolving needs of the data center sector. “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,” he stated. Richmond also highlighted the company's collaborative efforts with several leading customers in developing the ADH converters, indicating a commitment to expanding the product line with additional power levels and form factors.

The ADH series is designed with advanced liquid-cooled baseplates to optimize thermal management, addressing one of the critical challenges faced by high-density power solutions. Its standard form factor allows for the connection of multiple modules in parallel, facilitating significant power scaling. Moreover, the design incorporates safety-critical insulation necessary for systems operating at hazardous input voltage levels, ensuring both performance and safety in demanding environments.

In addition to the ADH series, Advanced Energy is also offering the NDQ series of ultra-efficient non-isolated bus converters, which convert 50 V DC to 12 V DC. The newly developed Hot Swap Control (HSC) module enhances system reliability by managing inrush current and providing additional protective functions. Together, these innovations enable higher power levels and increased power density, fulfilling the requirements for megawatt-capable AI server racks.

Advanced Energy's introduction of the ADH series of DC-DC converters marks a pivotal moment for the data center industry, particularly as the demand for AI-driven applications continues to escalate. With its focus on high efficiency, power density, and safety, the company is well-positioned to lead the charge in 800 V DC power solutions. As Advanced Energy continues to innovate and expand its portfolio, it remains committed to meeting the critical demands of this emerging power paradigm.
