Revolutionary Control Techniques for AI Data Center Efficiency
At a recent major industry event, Navitas Semiconductor (Nasdaq: NVTS) unveiled their groundbreaking control technique known as ‘IntelliWeave’. This next-generation technology aims to enhance power supply unit (PSU) efficiency exceeding 99%. With the surge in demand for artificial intelligence (AI) and cloud computing capabilities, the energy requirements for data centers continue to escalate. This makes energy efficiency a critical focus for designers and operators of data centers.
Understanding IntelliWeave Technology
The IntelliWeave control technique stands at the forefront of innovation, harnessing the potential of gallium nitride (GaN) and silicon carbide (SiC) semiconductors. This patented approach incorporates advanced digital controls to manage power conversions effectively. By enabling precise current sharing and rapid dynamic response, IntelliWeave ensures that energy usage is optimized while maintaining minimal phase errors. The dual-loop and dual-feed-forward interleaving control developed for this technology achieves absolute zero voltage switching (ZVS) across the entire load range, which is crucial for maximizing efficiency.
Dramatic Reductions in Power Losses
One of the standout features of IntelliWeave is its ability to significantly reduce power losses. The digital control mechanism for Critical Conduction Mode (CRM) interleaving Power Factor Control (PFC) results in a remarkable 30% decrease in power losses compared to legacy Continuous Conduction Mode (CCM) solutions. This combination, partnered with high-power GaNSafe power integrated circuits (ICs), has demonstrated its capabilities by achieving peak efficiency levels of 99.3% during testing with a 500 kHz GaN-based interleaving 3.2 kW CrM PFC PSU.
Engagement at IEEE ECCE 2024
The IEEE Energy Conversion Congress and Expo (ECCE) presented an ideal platform for Navitas to showcase IntelliWeave. Attendees gathered in Phoenix, Arizona, where experts gathered to discuss the latest developments in energy conversion technology, reflecting on the evolving needs of the industry.
