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.
