The 800 VDC revolution: the energy engine behind AI
Why the 800 VDC architecture, the sidecar and liquid cooling are turning AI data centers into industrial power plants — figures corrected to source.
White paper – From geometry to the watt
Huawei swaps Moore's geometric scaling for temporal scaling (the τ Law, LogicFolding). But stacking more compute into less volume concentrates power and heat, shifting the performance ceiling from the lithographer to the power engineer. High voltage near the chip, GaN/SiC and power-thermal co-design: the new frontier, and Premium's space.

What is an Electronic Fuse (eFuse) and Why Is It Replacing Conventional Fuses in Industrial Panels?
The electronic fuse (eFuse) detects overcurrents in microseconds, interrupts the circuit without blowing, and automatically resets. Unlike a conventional fuse, it indicates which channel has failed via an LED or digital signal, enables selective channel-by-channel protection, and eliminates the need for spare part stock.A solution that becomes more cost-effective than traditional fuses in installations with more than 3–4 faults per year, despite its higher unit cost.
