Anotace: PCB fuses are used widely in small power and small size electronic devices such as switch mode power supplies, chargers etc. They offer small size and low cost but their dependency of the track’s geometry make them imprecise. The aim of this research is to show an approach for improving the design procedure, leading to improved parameters and operation of the fuse. The suggested design is based on modeling with finite element method and numerical simulation. Experimental results validating this work are presented.
