A full silicon-carbide design has been published for an 18.4kW three-phase input, 52V output power module for compute racks. This is the highest-volume class of compute power supply and also the most easily overlooked: industry discussion is almost entirely about 800V, yet most GPU racks deployed between 2026 and 2029 still run on a 52V bus.
The value of an all-SiC design is raising efficiency and power density at the same time, so more power comes out of the same volume. For procurement, that means sustained demand for SiC MOSFETs, gate drivers, current-sense resistors, bus capacitors and thermal parts.
Kewei Technology stocks these power devices and passives and can quote the whole bill of materials as one package.
Kewei's take: what this means for procurement
Updates in power devices and supply designs directly affect thermal design and BOM cost. Budgeting efficiency, voltage rating and package margin at selection time is far cheaper than a later redesign.
