Abstract

Die Erfindung betrifft eine Gleichrichter-Brückenschaltung, insbesondere zum Gleichrichten der von einem Kfz-Generator erzeugten Spannung (U, V, W), die mehrere Zenerdioden (3-8) mit einer vorgegebenen Zenerspannung umfasst. Der Schutz spannungsempfindlicher Bauelemente vor Überspannung kann verbessert werden, wenn eine zusätzliche Zenerdioden-Anordnung (13, 14) vorgesehen ist, die parallel zur Gleichrichter-Brückenschaltung (12) geschaltet ist.
