Technical Prowess: Powering the AI Revolution with GaN and SiC
Navitas Semiconductor's new product portfolio is a testament to the power of wide-bandgap materials in high-performance computing. The core of this innovation lies in two distinct categories of power devices tailored for different stages of Nvidia's 800 VDC power architecture:
Firstly, 100V GaN FETs (Gallium Nitride Field-Effect Transistors) are specifically optimized for the critical lower-voltage DC-DC stages found directly on GPU power boards. In these highly localized environments, individual AI chips can draw over 1000W of power, demanding power conversion solutions that offer ultra-high density and exceptional thermal management. Navitas's GaN FETs excel here due to their superior switching speeds and lower on-resistance compared to traditional silicon-based MOSFETs, minimizing energy loss right at the point of consumption. This allows for more compact power delivery modules, enabling higher computational density within each AI server rack.
Secondly, for the initial high-power conversion stages that handle the immense power flow from the utility grid to the 800V DC backbone of the AI data center, Navitas is deploying a combination of 650V GaN devices and high-voltage SiC (Silicon Carbide) devices. These components are instrumental in rectifying and stepping down the incoming AC power to the 800V DC rail with minimal losses. The higher voltage handling capabilities of SiC, coupled with the high-frequency switching and efficiency of GaN, allow for significantly more efficient power conversion across the entire data center infrastructure. This multi-material approach ensures optimal performance and efficiency at every stage of power delivery.
This approach fundamentally differs from previous generations of AI data center power delivery, which typically relied on lower voltage (e.g., 54V) DC systems or multiple AC/DC and DC/DC conversion stages. The 800 VDC architecture, facilitated by Navitas's wide-bandgap components, streamlines power conversion by reducing the number of conversion steps, thereby maximizing energy efficiency, reducing resistive losses in cabling (which are proportional to the square of the current), and enhancing overall system reliability. For example, solutions leveraging these devices have achieved power supply units (PSUs) with up to 98% efficiency, with a 4.5 kW AI GPU power supply solution demonstrating an impressive power density of 137 W/in³. Initial reactions from the AI research community and industry experts have been overwhelmingly positive, highlighting the critical need for such advancements to sustain the rapid growth of AI and acknowledging Navitas's role in enabling this crucial infrastructure.
