Abstract
A control circuit for turning on a power semiconductor switch includes an input that receives a signal characterizing a switch-on behavior of the power semiconductor switch. A phase detection circuit detects two or more phases of the switch-on behavior of the power semiconductor switch in response to the signal that characterizes the switch-on behavior of the power semiconductor switch. The phase detection circuit is coupled to generate a phase signal that indicates which of the two or more phases the power semiconductor switch is currently running through. A variable current source is coupled to supply a current with a variable level to a control input of the power semiconductor switch to switch on the power semiconductor switch. The control circuit is coupled 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.
