Abstract:
A vehicle electrical system includes: an active bridge rectifier which is connected to a generator via multiple phase terminals, and having terminals on the direct voltage side; a unit for recognizing load shedding at the active bridge rectifier and short-circuiting the phase terminals in a clocked manner, as the result of which a pulsed current is fed to the vehicle electrical system; a vehicle electrical system capacitor configured for smoothing the pulsed current; and a voltage limiting unit configured for clipping a voltage between the terminals of the bridge rectifier on the direct voltage side to a predefined maximum voltage.
