A method for controlling two electrically series-connected reverse-conductive (RC) IGBTs (RC-IBGT) of a half bridge is disclosed, wherein an operating DC voltage is applied across the series connection and one of the two series-connected reverse-conductive IGBTs operates in IGBT mode and another of the two series-connected reverse-conductive IGBTs operates in diode mode, and wherein each of the two reverse-conductive IGBTs has three switching states “+15V”, “0V”, “−15V”. The RC-IGBT T1 operated in diode mode does not go into the switching state (−15V) of highly charged carrier concentration, but instead into a state of medium charge carrier concentration associated with the switching state “0V”, and not into the switching state “−15V”, as is known from conventional methods. This reduces the reverse-recovery without adversely affecting the forward voltage.
