摘要

在NPC 2型IGBT电源模块的标准稳健性评估期间，观察到三级NPC 2拓扑结构中未描述的效应。对这种影响的完整描述有助于保护该拓扑中的IGBT电源模块免受爆炸的影响，并有助于事后分析以了解其原因。充分了解这种影响，可以增加逆变器的使用寿命，减少资格认证的时间和成本。

Investigation of short circuit in a IGBT power module with Three-Level neutral point clamped type 2 (NPC2, T-NPC, mixed voltage) topology

During standard robustness evaluations of a NPC type 2 IGBT power module a non-described effect in a Three Level NPC 2 topology was observed. A full description of that effect can help to protect IGBT power modules in this topology against blow ups and can help in a post mortem analysis to understand the reason for this. With a full understanding of that effect the lifetime of the inverter can be increased and the time and costs for qualification reduced.
