Power Converter's IGBT Multi‐State Reliability Analysis for Low Failure Rate Operation

open access: yesIET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes a multi‐state reliability analysis for IGBTs in power converters, moving beyond the conventional two‐stage model with a constant failure rate and introduces a multi‐state Markov chain model for voltage source converters under different modulation scenarios.

Analytical modeling of device-circuit interactions for the power insulated gate bipolar transistor (IGBT) [PDF]

open access: yesIEEE Transactions on Industry Applications, 1990
The device-circuit interactions of the power insulated gate bipolar transistor (IGBT) for a series resistor-inductor load, both with and without a snubber, are simulated. An analytical model for the transient operation of the IGBT, previously developed, is used in conjunction with the load circuit state equations for the simulations.
