IntelliWeave’s patented digital control combined with high-power GaNSafe™ and Gen 3-Fast SiC MOSFETs enable PFC peak efficiencies to 99.3% and reduces power losses by 30% reduction compared to existing solutions
TORRANCE, Calif., Oct. 18, 2024 (GLOBE NEWSWIRE) -- At this month’s IEEE Energy Conversion Congress and Expo (ECCE), Navitas Semiconductor ( NVTS), the industry leader in next-generation GaNFast™ gallium nitride (GaN) and GeneSiC™ silicon carbide (SiC) power semiconductors, will introduce conference attendees to ‘IntelliWeave’ – an innovative patented new digital control technique for improving next generation AI data center power supply (PSU) efficiency.
In a world where ever-more energy is needed for the processing of artificial intelligence (AI) and cloud-based applications, minimizing power consumption has become a priority for data center architects and operators. Combining next-generation GaN and SiC semiconductors with new control technique strategies to power conversion plays a key role in achieving this goal.
IntelliWeave’s novel digital control enables highest system efficiencies with precision current sharing, ultra-fast dynamic response and minimal phase error. A patented dual-loop and dual-feed-forward interleaving control achieves absolute zero voltage switching (ZVS) across the full-load range to enable highest efficiencies. The digital control for Critical Conduction Mode (CRM) interleaving Totem Pole Power Factor Control (PFC) enables 30% reduction in power losses compared to existing Continuous Conduction Mode (CCM) solutions. The digital control combined with high-power GaNSafe power ICs has been proven on a 500 kHz GaN-based interleaving 3.2 kW CrM PFC PSU operating at 99.3% peak efficiency including EMI filter loss.
Taking place in Phoenix, Arizona from October 20th to 24th, IEEE ECCE 2024 features both industry-driven and application-oriented technical sessions and brings together practicing engineers, researchers and other professionals for interactive and multidisciplinary discussions on the latest advances in various areas related to energy conversion.
Tao Wei, Director, will present “Novel digital control for a GaN-based CrM interleaved TP PFC,” on Monday October 21st at 5.30pm in the main Expo Hall.
