Do IGBT modules explode?

However, IGBT modules often explode. Below, Xiaobian will analyze the case in detail. First, the IGBT explosion: For some reasons, the loss of the module is very large, the heat can not be dissipated, resulting in extremely high internal temperature, generating gas, breaking the shell, this is the so-called IGBT explosion.

Are IGBT modules the most vulnerable components in power electronic converters?

This paper 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.

Do IGBT power modules need a recalibration?

Additionally, there have been progressive technological improvements in IGBT power modules design during the last decade. Thus, to match the experimental results, a recalibration of the coefficients for the CIPS08 model is required.

How reliable are power IGBTs?

However, power IGBTs are also vulnerable components and their failure leads to severe malfunctions or destructive failures of the power converters [1 - 4]. Thus, the understanding of the failure mechanisms for IGBT modules and the availability of verified lifetime models are critical for determining the reliability of power converters.

Does temperature stress affect the failure mechanism of IGBT power modules?

It has been shown that temperature stress in the range of Δ T = 30 °C and Δ T = 40 °C still induces plastic deformations resulting in ageing of the IGBT power modules. However, it has been experimentally confirmed that the on-period has a strong impact and influences the failure mechanism.

What is IGBT (Insulated gate bipolar transistor)?

As the core device of energy conversion and transmission, IGBT (Insulated Gate Bipolar Transistor) has received the most attention. It is an effective way to im
