Abstract
The invention relates to a device for operating a voltage converter (), in particular a DC converter, of a motor vehicle, which voltage converter has at least two parallel-connected converter strands () which are connected between a high-voltage side () and a low voltage side () of the voltage converter () for converting the voltage, having at least one cooling device () carrying a coolant () and assigned to the converter strands (), wherein each of the converter strands () is assigned at least one temperature sensor (), comprising the following steps: a) detecting an input voltage, an output voltage and an operating current of each converter strand (), b) detecting a current converter strand temperature by means of the respective temperature sensor (), c) determining a respective coolant temperature as a function of the values detected in steps a) and b), d) comparing the two determined coolant temperatures (T_1, T_2) with each other and e) determining the serviceability of the temperature sensors () on the basis of the result of the comparison.
