There is provided a control system and method related to the use of insulated gate bipolar transistor (IGBT) devices in vehicles. An exemplary control method includes receiving a status signal that indicates a fault condition in the operation of an IGBT device of an affected converter. The exemplary method also includes sending a control signal that turns off all IGBTs of the affected converter. The exemplary method additionally includes receiving a second status signal for each of the IGBTs that indicates whether each of the IGBTs successfully turned off. The exemplary method further includes generating an indication that the fault condition relates to a saturation condition or a power supply being outside a designated range, depending on a duration of the fault signal.
