Self-adaptive soft turn-on of power switching devices

An embodiment of a control circuit is proposed for turning on a power switching device, the switching device turning on in response to a control signal exceeding a threshold value. The control circuit includes pre-charging means for providing the control signal at a pre-charging value not reaching the threshold value, and soft turn-on means for gradually increasing the control signal from the pre-charging value to a turn-on value exceeding the threshold value; the pre-charging means includes means for sensing an indication of the threshold value, and means for setting the pre-charging value according to the sensed threshold value.
