Abstract: An inverter unit. The inverter unit includes: a switch; an intermediate circuit; and a component. The inverter unit is configured to switch the switch on the basis of a predetermined switching sequence in order to drain the intermediate circuit. The predetermined switching sequence is configured to generate a current drop in the intermediate circuit at a substantially constant change in order to introduce a thermal energy, generated by a short circuit, into the inverter unit in order to determine an aging of the component.

Abstract: A circuit arrangement, an electrical system, and a method for determining barrier layer temperatures of gate-controlled semiconductor components. First and second semiconductor components of the circuit arrangement are connected in parallel and activated using a gate control circuit which, in an active forward mode of the two semiconductor components, varies a first gate voltage of the first semiconductor component using a first signal, and to varies a second gate voltage of the second semiconductor component using a second signal that is opposite the first signal. An evaluation unit of the circuit arrangement is configured to use first and second current measuring devices to measure first and second gate currents of the first and second semiconductor components, respectively, and to determine in each case, based on the particular varied gate voltages and the respective corresponding gate currents, respective barrier layer temperatures of the two semiconductor component.

Abstract: A circuit arrangement, a semiconductor module, an electrical system, and a method for optically outputting information using a MOSFET. The circuit arrangement includes a MOSFET with an optical interface and a gate control circuit. The optical interface is configured to guide light, generated by an inverse diode of the MOSFET, into surroundings of the MOSFET. The gate control circuit is configured to receive an input signal representing information to be output using the circuit arrangement, and to generate from the input signal an output signal representing the information to be output. The gate control circuit varies the gate-source voltage of the MOSFET in a reverse mode of the MOSFET based on the output signal to vary a light emission of the inverse diode of the MOSFET in a corresponding manner, so that an output of the information to be output takes place via the optical interface of the MOSFET.

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.
