Igbt failure reasons

Web6 jan. 2024 · Abstract: This article focuses on failure modes and lifetime testing of IGBT modules being one of the most vulnerable components in power electronic converters. IGBT modules have already located themselves in the heart of many critical applications, such as automotive, aerospace, transportation, and energy. WebIGBT damage is the most common cause of sub-module failure , generally due to short-circuit faults or open-circuit faults . Compared to the IGBT short-circuit fault, the IGBT open-circuit faults can last for a long time without being detected, which can deteriorate the output of the MMCs and can make the capacitors in the faulty SMs over-charged [ 8 ].

WebIGBT. If the short circuit is applied to an IGBT that is already conducting, the dv/dt resulting from the rapid de-saturation of the IGBT would boost the gate voltage of the IGBT and results in higher peak SC current (Fig 5 & 6). The increased peak current would increase the power dissipation and could cause IGBT failures. WebThe main causes of failure of the welded IGBTs are chip damage and package damage [12].
