Abstract
The disclosure relates to a method and a control device for controlling at power semiconductor switches connected in parallel for switching a total current. The semiconductor switches each have a gate terminal. An input terminal for feeding the total current, an output terminal for discharging the total current, and a joint control terminal for receiving a joint control signal that has the state ‘disconnect’ or ‘connect’ are provided. The power semiconductor switches are each connected between to the input terminal and the output terminal. At least one ascertainment unit is designed to receive the joint control signal, ascertain individual control signals in accordance with the joint control signal to control the individual power semiconductor switches, and output the individual control signals to the gate terminals of the power semiconductor switches. The individual control signals each have the state ‘disconnect’ or ‘connect’ and differ at least temporarily.
