    摘要: Bahnantriebe, die von einem Wechselspannungsnetz (1) oder von einem Gleichspannungsnetz (2) mit unterschiedlichen Spannungen gespeist werden, wandeln diese Speisespannungen mittels 2Quadrantenstellern (St1 - St4), die bei Wechselstromspeisung als parallelgeschaltete 4Quadrantensteller und bei Gleichstromspeisung als Aufwärts- oder Abwärtssteller betrieben werden, in eine möglichst konstante Zwischenkreisgleichspannung (UD) um. Zur Reduktion von Oberschwingungen bei Gleichstromspeisung sind die 2Quadrantensteller (St1 - St4) über je einen induktiven Widerstand (L1 - L4) und Schalter (S8 - S11) an einen positiven Pol (P) eines Gleichspannungszwischenkreises (11) anschließbar.
