Future automotive power supply systems must be fail-operational. Even short voltage disturbances at safety-relevant components due to switching events may be critical. The tripping of melting fuses and semiconductor-based electronic fuses (eFuses) cause serious switching events that may affect the overall power supply system. While non-automated vehicles were mainly equipped with melting fuses and voltage drops could be tolerated, future automated vehicles will be equipped with eFuses to meet functional safety requirements. Especially the behavior and impact of eFuses is not well understood today. In this paper the influence of switching events caused by tripping melting fuses and eFuses on the power supply voltage stability is investigated and both fuse types are compared. For this purpose, simulation models of automotive melting fuses and eFuses were developed and validated. The new models, in contrary to the known fuse models, focus on accurate modeling of the tripping behavior. Based on simulation and measurements, both fuse types are analyzed and their impact on other system components is investigated. It has been found that both melting fuses and eFuses might produce significant over-voltages at other loads. Parameter studies show, how to mitigate critical over-voltages.
