Abstract
A method and related apparatus drives a first semiconductor switching element, the load path of which is connected in series with a load path of a second semiconductor switching element in a half-bridge circuit and which is driven in the on state or in the off state according to switching signals transmitted via a transmission channel. The method includes detection of a load current through the half-bridge circuit, and repetition of the previous switching signal if the load current exceeds a predetermined maximum threshold value.
