A signal transmission system is used to drive at least one power semiconductor switch (S<SUB>1</SUB>, S<SUB>2</SUB>, . . . , S<SUB>n</SUB>) from a controller ( 11 ). The controller ( 11 ) can transmit at least one control signal to at least one modulator (M<SUB>1</SUB>, M<SUB>2</SUB>, . . . , M<SUB>n</SUB>) using at least one first transmission path ( 3 ). Each power semiconductor switch (S<SUB>1</SUB>, S<SUB>2</SUB>, . . . , S<SUB>n</SUB>) is connected to a respective control electrode driver stage (G<SUB>1</SUB>, G<SUB>2</SUB>, . . . , G<SUB>n</SUB>) and the at least one modulator (M<SUB>1</SUB>, M<SUB>2</SUB>, . . . , M<SUB>n</SUB>) can transmit at least one drive signal to each of the control electrode driver stages (G<SUB>1</SUB>, G<SUB>2</SUB>, . . . , G<SUB>n</SUB>) using a respective second transmission path ( 4 ). At least one control signal and/or a drive signal can be transmitted using electromagnetic radiation and the associated transmission path ( 3, 4 ) is wireless.
