  • Patent number: 7817392
    Abstract: An Insulated Gate Bipolar Transistor (IGBT) fault protection system is provided. The fault protection system includes a GVPA, a gate voltage clamper, and a soft-off unit. The GVPA analyzes a gate voltage pattern of an IGBT to determine whether or not a fault has occurred. The gate voltage clamper prevents an increase in a gate voltage of the IGBT according to an output signal that the GVPA outputs when a fault has occurred. The soft-off unit softly turns off the IGBT according to an output signal that the GVPA outputs when a fault has occurred.
