Abstract

A drive circuit for a power semiconductor circuit may include input contact means for inputting a control signal, the control signal representing a switching command for the power semiconductor circuit, and also at least one output contact means, to which the power semiconductor circuit is connectable and which serves for outputting a switching signal to the power semiconductor circuit. Furthermore, the drive circuit comprises current path connection means for connecting the drive circuit to a current path to be switched by the power semiconductor circuit, and means for galvanically isolating the input contact means from the output contact means and the current path connection means. Circuit means which output a switching signal that switches on the power semiconductor circuit if a control signal representing the switch-on command for the power semiconductor circuit is input at the input contact means and also voltage is present at the current path connection means.
