  • Patent number: 11894838
    Abstract: The invention relates to a device for controlling a plurality of semiconductor circuit breakers by means of driver voltages for the synchronous operation of a plurality of loads in the high-voltage range, where the driver voltages can be provided by a transformer. According to the invention, the driver voltages for the semiconductor circuit breakers are tapped from a single secondary winding of the transformer, where electronic voltage level converter circuits are provided to obtain the driver voltages from the secondary winding of the transformer at the required magnitude.
