Abstract: A method and device for adapting temperatures of semiconductor components. The device includes a first and second semiconductor component, and an evaluation unit. The evaluation unit is configured to ascertain a first and second temperature of the first and second semiconductor component, respectively, calculate a first and second temperature deviation, which represents a deviation of the first and second temperature from a reference temperature, respectively, and adapt a first gate voltage of the first semiconductor component and/or a second gate voltage of the second semiconductor component until the first temperature deviation and the second temperature deviation are smaller than or equal to a predefined maximum allowable temperature deviation from the reference temperature. The adaptation takes place only when a predefined allowable control range for the respective gate voltage is not exceeded, and when the first temperature and/or the second temperature is/are greater than the reference temperature.

Abstract: A device configured for rotary speed measurement includes a speed transmitter on which segments are distributed across a radial circumference and a sensor that is substantially stationary relative to the speed transmitter. A method for determining the rotary speed of the device includes continuously determining pass-through times of all segments relative to the sensor, continuously determining revolution times of the speed transmitter by summing the pass-through times of all segments over a complete revolution, and continuously determining the speed from the revolution times. The revolution times are determined after each pass-through of a segment relative to the sensor and the most current pass-through times of all segments are used for determining each revolution time. Since the time for a full revolution is calculated for each segment respectively, differences in the length of individual segments due to production do not have any negative influence on the calculation of speed.
