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.

Method and device for adapting temperatures of semiconductor components

A semiconductor power module including first and second power transistors situated in parallel between first collector and first emitter strip conductors. A first connection surface of each of the power transistors is electroconductively connected to the first collector strip conductor, and a second connection surface of each of the power transistors is electroconductively connected to the first emitter strip conductor, so that a current flowing between the first collector strip conductor and the first emitter strip conductor is divided between the power transistors when the power transistors are each conductively connected via an applied control voltage. A first external power contact is directly contacted with the first collector strip conductor at a first contact area, a second external power contact is contacted with the first emitter strip conductor at a second contact area via a first connecting element, and the second contact area is positioned asymmetrically between the power transistors.

Semiconductor power module

A device for converting electrical energy, including at least one switching-type semiconductor component, a cooling path for cooling the semiconductor component, and a device for determining a degradation of the cooling path based on a current having a predetermined current intensity that flows through the component. The device provides that the semiconductor component includes an optically active semiconductor material, which generates light having a brightness that is dependent on a temperature of the semiconductor component when the semiconductor component is traversed by current having a predetermined current intensity, and the device for determining the degradation includes a brightness sensor for recording the brightness of the generated light. The device has the advantage that the device for determining the degradation and the component are inherently galvanically isolated, and the degradation can be determined at a high resolution.
