This AI selector guide simplifies the selection process, helping designers quickly find solutions that achieve high efficiency while meeting crit density, reliability, and performance. Offering 10 % lower on-resistance than competing devices, the SiC3231E. Server Power Supply Units (PSUs) have evolved to employ advanced wide bandgap devices like silicon-carbide MOSFETs and gallium-nitride FETs, allowing for higher switching frequencies and fewer magnetic components. Server PSUs are also shifting from traditional mechanical relays to solid-state. Designed for traditional server configurations, conventional power-supply units (PSUs) can't efficiently keep pace with the demands of GPU-based AI accelerators. To meet evolving workload requirements, data center operators need power-delivery systems that scale within existing thermal and physical. The increasing power demands of AI workloads are driving a shift in data center rack architectures. Current single-phase PSUs are evolving to high-power three-phase AC and fully centralized HVDC systems for efficiency. Infineon's CoolSiC™ and CoolGaN™ technologies excel in supporting these. Materials used in AI data centers encompass a range of raw resources critical for constructing, powering, and operating facilities designed to support the high-density computational demands of artificial intelligence workloads, including structural materials like steel and concrete for robust. What these power supplies all have in common is a power-factor-correction PFC section, that rectifies the AC to DC at near unity power factor with an output voltage of 400 V, followed by a DC-DC converter which converts this 400 V to 48 V or 12 V for use within the system.
