Method for controlling heater resistor, involves controlling heat of heating resistor by pulse-width modulating signal, where pulse-width modulating signal controls active component connected in series with heater resistor

摘要

The method involves controlling the heat of the heating resistor (R-h) by pulse-width modulating signal. The pulse-width modulating signal controls an active component (3) connected in series with the heater resistor. The pulse-width modulating signal is guided to the active element by a controller (2). The controller has a degenerative feedback of a point between the heating resistor and the active element. An independent claim is included for a device for controlling a heater resistor, particularly for operating a seat heater in a vehicle.
