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.

Device for controlling semiconductor circuit breakers in the high-voltage range

An arrangement, comprising a heat-emitting resistor, a control device for switching the resistor and a component that is at a potential without direct reference to a drive voltage. The resistor is arranged in spatial proximity to the component, and has a first and a second partial resistor connected in series. The control device includes at least one switching device for switching the heat-emitting resistor. The first partial resistor, the switching device and the second partial resistor are connected in series in the stated order and form a series connection. The first partial resistor and the component form a first partial capacitance and the second resistor and the component form a second partial capacitance. The partial capacitances are formed in such a way that upon the switching of the resistor a current flowing in the first partial capacitance is at least partly taken up by the second partial capacitance, or vice versa.
