Method and device for controlling a semiconductor switch
A method for controlling an electronic semiconductor switch connected in a load current circuit, the semiconductor switch being connected between an input terminal routed to a source and an output terminal of the load current circuit routed to a load. A control circuit is connected to a supply voltage and has a bridge circuit connected on the primary side to a transformer and to the supply voltage. A load circuit is connected to the transformer on the secondary side, the load circuit having a driver circuit for the semiconductor switch. A threshold value signal is routed to the bridge circuit on the control side. The bridge circuit generates a primary signal which is transmitted as a secondary signal to the load circuit that is galvanically isolated from the control circuit, and wherein the secondary signal is fed to the driver circuit, which generates a drive signal for the semiconductor switch.
