description A control device for driving a bipolar switchable power semiconductor component is designed to apply an electrical voltage to a gate terminal of the power semiconductor component and to reduce the electrical voltage for turning off the power semiconductor component from a first voltage value to a second voltage value. The control device is designed, for turning off the power semiconductor component, firstly to reduce the electrical voltage from the first voltage value to a desaturation value and then to reduce the electrical voltage from the desaturation value to the second voltage value. The desaturation value is greater than a pinch-off voltage of the power semiconductor component.
