  • DESIGN AND FABRICATION OF PRINTED FUSE
    Publication number: 20230187160
    Abstract: A power fuse for protecting an electrical load subject to transient load current cycling events in a direct current electrical power system is provided. The power fuse includes at least one fuse element assembly that includes one or more substrates, one or more sets of weak spots, and a conductor. The weak spots are formed on the substrates, and the substrates are longitudinally spaced apart from one another along the conductor. The conductor is separately provided from the substrate and the weak spots. The conductor includes one or more strips of metal having no stamped weak spot openings therein and therefore avoiding thermal-mechanical fatigue strain in the conductor when subjected to the transient load current cycling events. The conductor includes connector sections that are attached to respective ones of the sets of weak spots, and extending sections coupling the connector sections.
