Abstract: 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.

Abstract: Power system and method for providing electrical power are provided. The system includes a traction system and auxiliary equipment coupled to a power bus. The traction system includes one or more electromotive machines having a first type of stator winding that provides protection relative to voltage spikes expected at the traction stator under a first voltage level appropriate for the traction system. The auxiliary equipment includes one or more electromotive machines having a second type of stator winding that provides protection relative to spikes expected at the auxiliary stator under a second voltage level lower than the first voltage level. Inverter circuitry is coupled to drive the auxiliary equipment, and signal-conditioning circuitry is provided to attenuate voltage spikes produced by the inverter circuitry. The power bus is operated at the first voltage level, and the voltage spike attenuation is sufficient to protect the auxiliary stator.
