摘要
研究了 IGBT在过电流的状态下 ,静态输出特性及动态电流和电压波形的变化规律 ,提出了 IGBT极限电流与极限功耗的识别方法 ,阐明了因过电流和过损耗致使
This paper focuses on the static output characteristics as well as the changing laws of dynamic waveforms of device current and voltage in the state of over current.An identification method for IGBT's critical current and critical power loss is first proposed.The mechanism of device failure from the over current and power loss is analyzed.
