摘要:
A method analyzes an operation of a power semiconductor device. The method includes: providing a set of reference voltages of the power semiconductor device and a set of corresponding reference currents; measuring an on-state voltage and a corresponding on-state current of the power semiconductor device to obtain a measurement point; adapting the set of reference voltages by adapting two of the set of reference voltages lying closest to the measurement point by extrapolating the measurement point; and using the adapted set of reference voltages to analyze the operation of the power semiconductor device. The extrapolation is based on a predefined reference increment current and a predefined reference increment voltage.
