Gesteuerte Gleichrichterbrücke mit Überspannungsschutz |
摘要 |
The present invention relates to a controlled rectifier bridge for a generator comprising several phase windings and an excitation winding, wherein said rectifier bridge is made in the form of an automatic rectifier bridge with field-effect MOS transistors. In order to use such a rectifier bridge with a faster load decrease, and hence with a load-dump voltage, a voltage protection circuit is provided for returning into the battery the energy which has built up in the excitation winding upon a rapid cutoff, thus unloading the excitation winding. In case of a rapid decrease of the load, the windings of the generator are short-circuited by the corresponding triggering of the low- or high-side transistors.
