Introducing the Groundbreaking 8.5 kW Power Supply by Navitas
Navitas Semiconductor, a leader in next-generation semiconductor technologies, has unveiled an innovative 8.5 kW power supply unit (PSU). This advanced unit is powered by gallium nitride (GaN) and silicon carbide (SiC) technologies, achieving an impressive 98% efficiency, setting a new benchmark for AI and hyperscale data centers.
Key Features of the 8.5 kW PSU
This new AI-optimized power supply boasts several cutting-edge features that help it stand out in the competitive landscape. It is compliant with Open Compute Project (OCP) and Open Rack v3 (ORv3) specifications, highlighting its adaptability and commitment to industry standards. The power supply utilizes high-power GaNSafe technology alongside Gen-3 Fast SiC MOSFETs, arranged in a 3-phase interleaved topology to maximize performance.
Exceptional Efficiency and Reliability
One of the PSU’s most notable features is its transition to a 3-phase topology for PFC and LLC configurations. This change enables the lowest ripple current and electromagnetic interference (EMI) in the industry, making it an ideal choice for sensitive applications. Furthermore, the design reduces the required number of GaN and SiC devices by 25%, helping to lower overall costs while maintaining reliability.
Temperature and Voltage Ratings
The PSU functions effectively within an input voltage range of 180 to 264 Vac and operates at a temperature range from -5°C to 45°C. Its hold-up time is 10 ms at full capacity, with the potential for 20 ms through an extender, ensuring uninterrupted operation during power fluctuations.
Innovative GaNSafe Technology
The integration of GaNSafe technology is crucial for delivering safety and performance. This technology includes features like short-circuit protection with a maximum latency of 350 ns and up to 2 kV ESD protection across all pins. The elimination of negative gate drive and the ability to control slew rates add even more reliability to this power supply.
Designed for Future Applications
Navitas aims to continue its innovation journey with plans to enhance this PSU to 12 kW and beyond. As Gene Sheridan, CEO and co-founder, remarked, a significant number of data centers today are not equipped to manage the power demands of advanced servers, such as those featuring NVIDIA’s latest GPUs. This new PSU addresses these challenges head-on, making it a critical solution for the future of AI and hyperscale data centers.
