Abstract: Method and apparatus for controlling a turn-off power converter valve having at least two series connections. Each non-latching power semiconductor switch of this power converter valve has an active collector-emitter limiting circuit. When a rising edge of a drive signal that is provided arrives, a predetermined value of the reference limited voltage of the active collector-emitter limiting circuit is decreased to a low value and is increased to the predetermined value again during a turn-off operation. Using a switch-on command, it is possible to balance the voltage sharing on the non-latching power semiconductor switches of a turn-off power converter valve having at least two series connections.
