一种基于多级阳极电压检测的4500V压接式器件单管关断能力无损测试方案

The turn-off capability test for the single cell of power devices is of great significance to both the safe operation assurance and the destruction mechanism research. However, with present techniques, the device under test is supposed to be destroyed once the turn-off fault occurs. In this article, a robust nondestructive test scheme based on the multistage anode voltage detection for 4500 V sing...
