Abstract: A method and an arrangement of controlling a reverse-conducting IGBT (RC-IGBT) component in a circuit comprising a series connection of controllable switch components where at least one of the controllable switch components is an RC-IGBT and the other component is to be controlled to a conductive state. The method comprising applying a pre-trigger pulse to the gate electrode of the RC-IGBT during reverse conduction of the RC-IGBT at a first time instant (t1), the pre-trigger pulse corresponding to a turn-on gate pulse, applying a turn-on gate pulse at a second time instant (t2) to the other controllable switch component of the series connection for controlling the other controllable switch component to a conductive state such that the pre-trigger pulse and the turn-on gate pulse overlap, and ending the pre-trigger pulse after a delay time at the third time instant (t3), the delay time being the time period when the turn-on gate pulse and the pre-trigger pulse overlap.

Abstract: Unique systems, methods, techniques and apparatuses of a reverse-conducting IGBT (RC-IGBT) are disclosed. One exemplary embodiment is a circuit comprising a series connection of controllable switch components where at least one of the controllable switch components is an RC-IGBT. The circuit is operated by applying a pre-trigger pulse to the gate electrode of the RC-IGBT during reverse conduction of the RC-IGBT at a first time instant, the pre-trigger pulse corresponding to a turn-on gate pulse. Next, a turn-on gate pulse is applied at a second time instant to the other controllable switch component of the series connection for controlling the other controllable switch component to a conductive state such that the pre-trigger pulse and the turn-on gate pulse overlap, and ending the pre-trigger pulse after a delay time at the third time instant. The delay time is the time period when the turn-on gate pulse and the pre-trigger pulse overlap.
