摘要
Determining the temperature of a power semiconductor in an inverter (10) comprises switching a load current off and on and determining its value. If this lies within a given region the voltage drop at the semiconductor is determined and from this the temperature of the power semiconductor. Independent claims are also included for the following: (A) a circuit for the above; (B) an inverter comprising the above; and (C) determining a blocking layer temperature for a power semiconductor in an inverter.
