Abstract:
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.
