Design and verification of a simulation model for fuses with high-breaking capacity

This paper presents a new simulation model for fuses with high-breaking capacity. Especially when investigating protection concepts for high-power converters, fuse behavior is of major interest. Design basics and applications of modern fuses will be presented, followed by a detailed description of the modeling concept. The realization in a commercial simulation program is then discussed, accompanied by measurement results used for parameterization. Additional measurements are employed to verify and assess the accuracy of the model. Finally, the application of the model in complex drive systems is shown.
