Web众所周知，IGBT失效的主要原因是寄生SCR的锁定（Latch-up）和超结温tj工作出现的烧毁。（1）RBSOA的失效：在额定电压下关断箝位电感电流Ilm时，由于关断来自IGBT发射极的沟道电子电流，寄生PNP管发射极注入到高阻漂移区（PNP管的是基区）的少子空穴一部经过PNP管的基区从IGBT的发射极流出。 In electronics, a latch-up is a type of short circuit which can occur in an integrated circuit (IC). More specifically, it is the inadvertent creation of a low-impedance path between the power supply rails of a MOSFET circuit, triggering a parasitic structure which disrupts proper functioning of the part, possibly even leading to its destruction due to overcurrent. A power cycle is required to correct this situat…
