不均匀温度分布对压接式IGBT电极翘曲的影响

The pressure and junction temperature distribution within press-pack insulated gated bipolar transistors had been proven uneven due to the thermomechanical coupling effect caused by electrode warpage. However, the root reason for the electrode warpage remains unclear, and therefore leads to confusion in optimization. In this article, the influence of vertical and lateral temperature difference on ...
