Abstract: A resettable solid state fuse that automatically restores an interrupted circuit after an overcurrent event is cleared. The resettable solid state fuse can include one or more switching devices, such as, for example, a normally-on power semiconductor, and one or more positive temperature coefficient (PTC) resistive elements. The switching device is structured to extend the voltage rating of the resettable fuse, allowing the solid state resettable fuse to attain both a relatively elevated voltage rating and a relatively elevated electrical current rating while using a PTC resistive element. According to certain embodiments, the solid state resettable fuse can be tripped by a cascaded PTC resistive element, thereby providing a passive electronic device that can operate in the absence of electronic sensing, detection, and tripping, as well as without reliance on an auxiliary power supply.

Abstract: Technologies for providing DC arc protection in a DC socket include an electromagnet positioned in the DC socket configured to produce a magnetic field. The electromagnet is positioned to be adjacent to a contact region between one or more supply terminals of a DC socket and one or more prongs of a DC plug. As the DC plug is disconnected from the DC socket, a DC arc might form between one or more of the supply terminals and one or more of the prongs. The magnetic field produced by the electromagnet reduces the energy of the DC arc and reduces the time duration of the DC arc.
