Abstract
A power electronics system for an electric motor includes a first inverter package having a first housing defining a first enclosure and MOSFET pairs disposed within the first enclosure, wherein an output of each MOSFET of each MOSFET pair are coupled together and operable to be electrically coupled to a first end of a winding of the electric motor. The power electronics system further includes a second inverter package having a second housing defining a second enclosure and three IGBT pairs disposed within the second enclosure, wherein an output of each IGBT of each IGBT pair are coupled together and operable to be electrically coupled to a second end of the winding of the electric motor, and the IGBT pairs are cooled by immersion within the dielectric cooling fluid. A state selector circuit is operable to selectively electrically couple the second ends of the windings of the electric motor together.
