Abstract: The major topics of this thesis are investigations regarding the Self Turn-on. The dynamic feedback between the power- and the control-path of an IGBT (Insulated Gate Bipolar Transistor) depends on the collector-current and influences the switching and short-circuit behaviour. This is caused by an intrinsic controlled displacement current between the IGBT’s drift-region and its gate-junction. The physics behind this effect are based on a local change of the charge-carrier density in the drift-region below the gate-electrode.
