Navitas Semiconductor hosts ‘AI Tech Night’ event

Navitas Semiconductor (NVTS) will host an “AI Tech Night” event in Taipei, Taiwan, bringing together industry experts, supply chain partners, and technology developers for keynote speeches, demonstrations, and interactive discussions. The event will focus on how high-power GaNSafe and GeneSiC technologies are transforming AI data center infrastructure by overcoming efficiency and power density challenges to meet the growing power demands of AI and hyperscale data centers. Navitas will debut its next-generation OCP data center power supply unit reference design, which has been ‘designed for production’ and achieves the world’s highest power density, performance, and efficiency. With each GPU power exceeding 1,000W and AI cluster computing demand doubling every three months, traditional power supply technologies are struggling to keep pace with the evolving needs for energy efficiency and power density in AI infrastructure. Navitas’ GaN and SiC solutions will showcase the breakthrough of conventional architectural limitations and enable more efficient, high-density, and sustainable data center development. Navitas ‘AI Power Roadmap’ was created in 2023, focusing on next-generation AI data center power delivery. The initial PSU was a high-speed, high-efficiency 2.7 kW CRPS, which offered 2x higher power density and a 30% reduction in energy loss. A 3.2kW CRPS followed, achieving a 40% smaller size than best-in-class, legacy silicon solutions for power-hungry AI and Edge computing. Next was the world’s highest-power-density 4.5kW CRPS, achieving 137W/in3 and an efficiency of over 97%. In November 2024, Navitas released the world’s first 8.5kW AI data-center power supply powered by GaN and SiC that could meet 98% efficiency, complying with the Open Compute Project and Open Rack v3 specifications. Additionally, Navitas created IntelliWeave, a patented new digital control technique that, when combined with high-power GaNSafe and Gen 3-Fast SiC MOSFETs, enables PFC peak efficiencies of 99.3% and reduces power losses by 30% compared with existing solutions. Navitas will also highlight the world’s first mass-produced 650V Bi-Directional GaNFast power ICs and IsoFast high-speed isolated gate drivers. These technologies drive a paradigm shift from traditional two-stage to single-stage power topologies, optimizing data center power supply design, reducing form factors, and increasing rack space utilization.
