Abstract
This letter focuses on the accurate simulation of the turn-off current for high-voltage and high-power IGBT devices and proposes a modeling method of transient analysis model (TAM) for IGBT devices based on the nondual relationship of the switching process. Combined with the structural features of the IGBT chip, the carrier storage effect is analyzed and the analytical expression of di/dt during the turn-off process is corrected. Compared with the existing dual modeling methods, the accuracy of the nondual modeling method for di/dt during the turn-off process has been greatly improved.
