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.
Industrial Power Converter Selection Guide: 5 Critical Parameters
5 critical parameters most engineers overlook when selecting an industrial power converter — and the most common sizing errors. Practical guide based on 900+ designs manufactured in Barcelona, Spain.

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.
Thermal Design in Power Electronics
Thermal failure accounts for over half of all premature faults in power electronics. This article covers the fundamentals of modern thermal design — thermal budget, Arrhenius law, thermo-mechanical fatigue and cooling technology hierarchy — alongside the concurrent DFR methodology that Premium SA applies from the concept phase in SiC/GaN converters for railway, defence and industrial applications.

Premium SA at OCP EMEA Summit 2026 Barcelona: Industrial Discipline for the 800 V DC Era
The Technical Inflection: From 48 V to 800 V DC For fifteen years, the server rack lived comfortably within 48 V bus architectures. OCP Open Rack v3 (ORv3) consolidated that standard and allowed the industry to scale deployments to 80–100 kW per rack.
