Yaqub, Imran and Li, Jianfeng and Johnson, Christopher Mark (2015) Dependence of overcurrent failure modes

Insulated gate bipolar transistor (IGBT) modules which can fail to short circuit mode have great of applications in electricity network related fields. Single IGBT samples have been constructed with the standard Al wire bonding, flexible printed circuit board (PCB) interconnect and sandwich structure technologies. The overcurrent failure modes of the constructed IGBT samples have been tested un...
