Der Einsatz von schnellschaltenden IGBTs in Niederspannungs- und Mittelspannungsanwendungen sowie Energieübertragungssystemen stellt an die Zuverlässigkeit der eingesetzten Halbleiter, der Isolationssysteme und die elektromagnetische Umgebung hohe Anforderungen. Daher ist eine aktive Beeinflussung der Schalteigenschaften des IGBTs von großem Interesse. Die Dissertation behandelt die Untersuchung neuartiger Ansteuerverfahren zur Regelung der Kollektorstromänderungsgeschwindigkeit während des Einschaltvorganges und der Kollektor-Emitter-Spannungsänderungsgeschwindigkeit während des Ausschaltvorganges. Weiterhin wird ein neues Verfahren zur Überspannungsbegrenzung beim Ausschalten des IGBTs vorgestellt und untersucht. Basierend auf einer Besch...
