Abstract:
1. A power electronics system for a powered system, the power electronics system comprising: a first IGBT module, including a plurality of first IGBTs as part of the first IGBT module, electrically connected to and configured to provide an electrical power signal to a traction inverter in the powered system, the first IGBT module having an electrical rating configured for use with the traction inverter; a second IGBT module, including a plurality of second IGBTs as part of the second IGBT module, electrically connected to and configured to provide an electrical power signal to an auxiliary inverter having a different electrical rating than the traction inverter in the powered system, the second IGBT module having an electrical rating configured for use with the traction inverter, wherein the second IGBT module is connected to the auxiliary inverter such that the electrical rating of the second IGBT module is acceptable for the auxiliary inverter; and a plurality of first gate drives each singularly connected to a respective one of the plurality of second IGBTs within the second IGBT module.
