Abstract
A motor vehicle electrical system which includes an electric machine, an active bridge rectifier, and at least one control device, the at least one control device being configured for converting an alternating voltage which is output by the electric machine at a number of phase connections into a direct voltage by controlling active switching elements of the bridge rectifier. An arrangement is provided configured for initiating a short circuit of at least two of the phase connections as soon as a signal characterizing the direct voltage exceeds an upper threshold value, and for deactivating the short circuit as soon as the signal characterizing the direct voltage subsequently falls below a lower threshold value. An evaluation device is provided configured for detecting a value of the direct voltage, for filtering the detected value, and for providing the filtered value as the signal characterizing the direct voltage.
