基于非触发电流下栅极电压的高压晶闸管在线结温提取

This letter proposes a junction temperature (Tj) extraction method for the high-voltage thyristors with the cathode short-circuiting structure. It has been studied that the gate voltage Vgk under nontrigger current is a practical temperature-sensitive electrical parameter (TSEP), which can be used for online Tj monitoring by calibrating the linear relationship between the gate voltage Vgk under no...
