Method for detecting an electrical fault in a generator assemblage, and means for implementation thereof

摘要

A method for identifying electrical faults in a generator assemblage, in particular of a motor vehicle, which assemblage includes a generator having a generator regulator and a rectifier having rectifier elements, the method encompassing ascertaining, in the context of at least one excitation current value of an excitation current through an excitation winding of the generator, at least one respective parameter that corresponds to a current conduction time proportion of at least one of the rectifier elements, and determining that an electrical fault exists if the at least one parameter deviates by more than a predetermined amount from an associated expected value. Also described is an apparatus for implementing the method.

1. A method for identifying an electrical fault in a generator assemblage, the generator assemblage including a generator having a generator regulator and a rectifier having rectifier elements, the method comprising:
ascertaining, in the context of at least one excitation current value of an excitation current through an excitation winding of the generator, at least one respective parameter that corresponds to a current conduction time proportion of at least one of the rectifier elements; and determining that an electrical fault exists if the at least one parameter deviates in more than predetermined fashion from an associated expected value.
