  • Patent number: 11758620
    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.

  • Patent number: 11665782
    Abstract: An assembly, comprising a heat-dissipating first resistor, control device for controlling the first resistor, as well as a grounded component, which lies on a potential without direct relation to a control voltage. The first resistor is arranged in spatial vicinity of the grounded component and comprising a first and a second connection. The control device comprises a first switching device and a second switching device. The first switching device, first resistor and second switching device form a series connection. A compensation device is configured such that in the On-state of the first resistor a voltage is applied between the first and second connection, wherein the resistor in the off-state is held on an in-between potential that lies between the first and the second potential and/or the control device is configured to trigger the first resistor in a pulse width modulated fashion, such that the first as well as the second switching device are switched synchronously.

  • Patent number: 9694649
    Abstract: Electric heating having at least one first resistance heating device and a second resistance heating device, at least one pulse width modulation device, which is capable of a pulse width modulated operation of the first resistance heating device and/or the second resistance heating device, as well as at least one switching device. For a heating operation, the switching device can be capable of selectively switching the first resistance heating device and the second resistance heating device between a first heating mode in which the first resistance heating device and the second resistance heating device are electrically connected in series, and a second heating mode in which the first resistance heating device and the second resistance heating device are electrically connected in parallel. A vehicle having electric heating as well as to a method for controlling electric heating is also provided.
