ABSTRACT:
A semiconductor switching element has a control connection and a load path, with the load path connected in series with a load and a supply voltage is applied across the series circuit. The semiconductor switching element is actuated by providing a first charging current at the control connection, and providing a second charging current at the first control connection, which is greater than the first charging current, when a voltage which is applied across the load path is less than a first threshold value, with the threshold value being between 20% and 80% of the supply voltage.
