The invention relates to a method (200) and a control device (1) for controlling at least two power semiconductor switches (LHS1..LHSn) connected in parallel for switching a total current (I_ges). The at least two power semiconductor switches (LHS1..LHSn) connected in parallel each have a gate terminal for controlling the respective power semiconductor switch (LHS1..LHS2). An input terminal (EA) for feeding the total current (I_ges), an output terminal (AA) for discharging the total current (I_ges), and a joint control terminal (S) for receiving a joint control signal (SI) that has the state 'disconnect' or 'connect' are provided. The at least two power semiconductor switches (LHS1..LHSn) connected in parallel are connected to the input terminal (EA) at the input end and to the output terminal (AA) at the output end. At least one ascertainment unit (EE) is designed to receive the joint control signal (SI) at the input end, ascertain at least two individual control signals (SI1..SIn) in accordance with the joint control signal (SI) in order to control the at least two power semiconductor switches (LHS1..LHSn), and output the at least two ascertained individual control signals to the gate terminals of the at least two power semiconductor switches at the output end. The at least two individual control signals (SI1..SIn) each have the state 'disconnect' or 'connect' and differ at least temporarily. |
