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.

The CKR-3600 by Premium PSU is a 3,600W modular redundant DC/DC converter with hot-swap modules, CAN/Modbus control and scalability up to 14.4 kW.
Why Multilayer PCB Design Makes the Difference in Power Electronics
In power electronics, reliability does not start with the schematic or component selection. It starts much earlier: with the structural decisions made at the PCB level.
