A control circuit for turning on a power semiconductor switch comprises an input which is configured to receive a signal that characterizes the switch-on behavior of the power semiconductor switch, a variable current source which is configured to supply a current with a variable level to a control input of the power semiconductor switch in order to switch on the power semiconductor switch, wherein the control circuit is configured to control the variable current source in a closed control loop in response to the signal that characterizes the switch-on behavior of the power semiconductor switch.
