Railway Power Solutions at InnoTrans 2026 | Premium PSU
Visit us at InnoTrans 2026, Hall 17 Stand 425. Our team will be available throughout the four days to discuss railway power solutions, onboard converters and DIN rail systems for demanding environments.

What is an Electronic Fuse (eFuse) and Why Is It Replacing Conventional Fuses in Industrial Panels?
El fusible electrónico (eFuse) detecta sobrecorrientes en microsegundos, corta el circuito sin fundir y rearma automáticamente. A diferencia del fusible convencional, indica qué canal ha fallado mediante LED o señal digital, permite la protección selectiva canal por canal y elimina el stock de recambios. Una solución que en instalaciones con más de 3–4 fallos al año resulta económicamente más ventajosa que el fusible tradicional, a pesar de su mayor coste unitario.

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.

Multilevel Inverters: NPC, FC, CHB and the Road to RDC-ML
From conventional two-level to neutral-point clamped, flying capacitor, cascaded H-bridge and reduced device count topologies — architectural synthesis for traction, grids and renewables

White paper – Wide bandgap semiconductors for next-generation data centers
The rapid growth of artificial intelligence, cloud computing and large-scale data processing is reshaping the energy requirements of modern data centers. In this new scenario, efficiency, power density and reliable operation under increasingly demanding loads have become key factors in power infrastructure design.
