传统上，功率半导体模块的状态监测是基于电测量的。声发射已经在许多其他应用中用于状态监测，但在功率半导体模块中是一个未知的现象。在本文中，作者提出了一个实验装置，用来证明声发射确实是由于功率半导体元件的开关而发生的。采用基于传播延迟的分析方法确定声发射源。
Traditionally, condition monitoring of power semiconductor modules has been based on electrical measurements. Acoustic emission has been utilized for condition monitoring in many other applications, but is an unknown phenomenon in power semiconductor modules. In this paper, the authors present an experimental setup used to show that acoustic emission does occur because of the switching of power semiconductor components. An analysis based on propagation delays is used to determine the source of the acoustic emission.
