As HVDC power infrastructure for AI data centers accelerates from architectural concept to deployment priority, Navitas Semiconductor is positioning power conversion as a defining constraint on next-generation compute growth. On Tuesday, the company introduced a 10 kW DC-DC power platform designed to address rising efficiency, density, and voltage requirements driven by artificial intelligence workloads, according to a company press release. The announcement comes as data center operators reassess power distribution strategies amid escalating rack-level demand and infrastructure complexity.
Navitas Semiconductor said the new platform reaches up to 98.5% peak efficiency while operating at a 1 MHz switching frequency, combining high performance with compact form factors aimed at hyperscale and AI-focused facilities.
Platform architecture targets high-voltage AI infrastructure
The 10 kW DC-DC platform uses 650 V and 100 V gallium nitride power semiconductors configured in a three-level half-bridge architecture with synchronous rectification. This design enables 98.1% efficiency at full load within a full-brick package measuring 61 × 116 × 11 mm. As a result, the platform achieves a power density of 2.1 kW per cubic inch, a metric that directly addresses space and thermal constraints inside modern AI racks.
Moreover, the platform supports both 800 V-to-50 V and +/-400 V-to-50 V conversion architectures at 10 kW. Navitas integrated auxiliary power and control components directly into the design, which simplifies system-level implementation while maintaining high-voltage compatibility. The company said the solution targets high-voltage direct current environments increasingly favored for AI data center deployments, where reduced conversion stages can improve efficiency at scale.
“The design platform enables the transition to HVDC data center power infrastructure, supporting the future power requirements of AI workloads that will demand between 100- and even 1,000-times more compute per query,” said Chris Allexandre, President and CEO of Navitas Semiconductor.
According to the company, this design focus aligns with industry efforts to rethink power distribution as compute density increases. While alternating current architectures remain dominant, HVDC systems are gaining traction as operators seek to lower losses, simplify distribution, and accommodate higher rack-level loads.
Customer evaluations and industry showcase underway
Navitas said key data center customers are currently evaluating the 10 kW DC-DC platform through collaborative development programs. These evaluations are expected to inform future product refinements as AI deployments move from pilot phases to full-scale infrastructure builds.
In addition, the company plans to showcase the platform at the Applied Power Electronics Conference in San Antonio, Texas, scheduled for March 22–26. The conference serves as a key industry venue for power electronics innovation, bringing together semiconductor suppliers, system designers, and infrastructure operators.
Navitas develops gallium nitride and silicon carbide power semiconductor technologies for applications spanning AI data centers, computing platforms, energy infrastructure, and industrial electrification. The company continues to emphasize wide bandgap materials as central to meeting efficiency and power density targets across these markets.
Broader partnerships reinforce global expansion strategy
Beyond the platform launch, Navitas has expanded its strategic footprint through multiple partnerships and product initiatives. The company recently announced a significant expansion of its distribution agreement with Avnet, naming Avnet as a global strategic distribution partner for its gallium nitride and silicon carbide semiconductor portfolio. This move supports Navitas’ strategy to consolidate distribution channels while extending global market reach.
Separately, Navitas entered a long-term strategic partnership with Cyient Semiconductors to advance gallium nitride adoption in India. The collaboration focuses on developing high-voltage products across multiple sectors, reinforcing the company’s presence in emerging semiconductor ecosystems.
Navitas has also made available samples of new high-voltage silicon carbide power semiconductors aimed at improving performance in data centers and industrial electrification. In parallel, the company formed a long-term strategic partnership with GlobalFoundries to strengthen U.S.-based gallium nitride development and manufacturing, with production scheduled to begin in 2026.
Together, these initiatives underscore Navitas’ effort to align product innovation, manufacturing scale, and global partnerships as AI-driven power demand reshapes data center infrastructure.
