Full-SiC Design for a 110kW 3RU Compute Power Shelf
A full silicon-carbide reference design has been published for a 110kW, 3RU power shelf for compute racks. A shelf aggregates several supply modules into one high-density unit, so the PFC, DC-DC and output stages all run at high current.

A full silicon-carbide reference design has been published for a 110kW, 3RU power shelf for compute racks. A shelf aggregates several supply modules into one high-density unit, so the PFC, DC-DC and output stages all run at high current.
For procurement this means high volumes of SiC MOSFETs, gate drivers, high-current inductors, bus capacitors and precision sense resistors, all with tight thermal requirements. Parts in this class usually carry longer lead times than generic passives.
Kewei Technology can supply and quote the full bill of materials for this kind of power shelf, including qualified alternatives for long-lead items.
Kewei's take: what this means for procurement
Power devices need more supply stability than ordinary parts. Keep at least two interchangeable options and confirm that package and thermal behaviour match.
