Abstract: An apparatus is provided for protecting high-voltage electrical connections, in particular in vehicles. A fuse for interrupting a line includes a conduction coil, which is designed to have a conduction current on the line flowing through the conduction coil and to thereby generate a magnetic field. Furthermore, the includes a control coil, which is magnetically coupled to the conduction coil, and a circuit breaker, which is designed to interrupt the line depending on a field intensity of the magnetic field. In addition, the fuse includes a control unit, which is designed to determine a control current through the control coil in order to vary the field intensity of the magnetic field, and thus to cause or suppress an interruption of the line by way of the circuit breaker.

Abstract: A system includes a vehicle and an induction charging unit, where the induction charging unit includes a primary coil and the vehicle includes a secondary coil. During a charging operation in a charging position, electric power is inductively transmissible from the primary coil to the secondary coil, in the charging position, the secondary coil being situated in a preferred spatial position area with respect to the primary coil, such that, for setting the charging position, by means of electromagnetic distance and angle measuring, by triangulation, the system detects a location position which describes a time-dependent spatial position of the secondary coil with respect to the primary coil. Moreover, by means of the location position and the charging position, the system detects at least a partial travel trajectory, along which the location position of the charging position can be approximated.

Abstract: A method for the supply of an electrical component with electric power using an inductive charging system having a primary coil unit and a secondary coil unit, where the electrical component is connected on a secondary side corresponding to the secondary coil, includes setting a rough position of the secondary coil unit relative to the primary coil unit to establish an electromagnetic coupling, displacing a primary coil in the primary coil unit relative to a primary ferrite in the primary coil unit in a preferred direction such that an electromagnetic coupling factor of the rough position of the secondary coil unit relative to the primary coil unit is increased, where the preferred direction lies in a plane of a planar basic shape of the primary ferrite, and changing a magnetically active surface area within the primary coil unit in the plane.
