More Information
Summary:The invention relates to an electrical on-board electrical system (150) for a motor vehicle (100), comprising a power distributor (152) and a plurality of first lines (154), which are designed to connect a corresponding plurality of electrical components (153) to the power distributor (152). Furthermore, the on-board electrical system (150) comprises a plurality of semiconductor-based first switching elements (204) for the respective plurality of first conductors (154), a particular first switching element (204) of a particular first conductor (154) being designed to interrupt the particular first conductor (154). Furthermore, the on-board electrical system (150) comprises a second line (155), which is designed to connect the distributor (152) to the on-board electrical system (150), and the on-board electrical system comprises a defining unit (205, 215, 151), which is designed to define or block a second current on the second line (155). The on-board power system (150) further comprises a control unit (201)
