    摘要： The invention relates to a rectifier module (40) for an active bridge rectifier, said module comprising two switch elements which are serially connected between two end terminals and between which a central tap is formed and comprising an actuation circuit with a monitoring unit (43), a synchronization unit (41), and an actuation unit. The monitoring unit (43) is designed to detect a measurement voltage and output a request signal if the measurement voltage exceeds an upper threshold. The synchronization unit (41) is designed to output a synchronization signal at a synchronization terminal (c) as long as the monitoring unit (43) outputs the request signal and to otherwise monitor the synchronization terminal (c) for a synchronization signal. The actuation unit is designed to at least partly switch one of the two switch elements to the conductive state during an actuation period if the monitoring unit (43) outputs the request signal and/or if the synchronization signal is detected by the synchronization terminal (c) monitoring process and optionally recognized as a valid synchronization signal. The invention likewise relates to an active bridge rectifier with corresponding rectifier modules (40), to a generator arrangement with such a bridge rectifier, to a corresponding motor vehicle electrical system, to a corresponding operating method, and to means for implementing said operating method.
