A motor vehicle with at least one energizable active current line, which at least sometimes carries an active current for the operation of at least one electrical consumer. At least one attenuation line layout is coupled by way of an inductive coupling to the energizable active current line in such a way that, in a protection area spaced apart from the active current line and the attenuation line layout, a magnetic field generated by the active current and/or a perturbation superimposed on the active current and/or a leakage current produced by the active current is attenuated by current flow induced in the attenuation line layout.

Motor vehicle

A circuit arrangement for an onboard network of a motor vehicle, includes a line having a first inductivity and connecting a component of a power electronics of an onboard network with an element, wherein the component is adapted for being clocked during operation of the power electronics at a clock frequency; and an absorber circuit assigned to the line and having a second inductivity and a capacitance, wherein the second inductivity of the absorber circuit is coupled with the first inductivity of the line.

Circuit arrangement

A motor vehicle having a vehicle body, which is formed at least in part from an electrically conductive material. An electrical system is arranged electrically insulated from the vehicle body and has a rectifier unit. An energy coupling device is arranged electrically insulated at the vehicle body for supplying electric energy for the electrical system. The energy coupling device has a coil for wireless magnetic coupling of an energy source that is external to the motor vehicle and provides an alternating magnetic field, wherein the coil is connected to the rectifier unit of the electrical system. An antenna unit is arranged at the vehicle body and is electrically insulated with respect to the electrical system. A decoupling device electromagnetically decouples the coil from the antenna unit.
