Abstract
An electronic switch includes switching modules to change a forward resistance of a semiconductor switch via a drive circuit depending on data exchanged via a data interface and depending on measurement values of a current sensor. The semiconductor switches of the switching modules are arranged electrically in parallel and a current through the electronic switch is divided among the semiconductor switches. The electronic switch controls a division of the current through the electronic switch among the semiconductor switches via the drive circuits by changing a forward resistance of the semiconductor switches, synchronously switches the semiconductor switches via the drive circuit and operates the semiconductor switches in a linear region in a time range of 1 μs to 10 μs upon a change between ON and OFF and a change between OFF and ON in such a way that the current through the switching modules is reduced in a controlled manner.
