Abstract

The invention relates to a method (200) and a control device (I) 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 an input end and to the output terminal (AA) at the output end.
