Abstract: A propulsion system includes a first portion and a second portion that are independently controlled from one another. The first portion includes a first inverter and a first electric motor. The second portion includes a second inverter, a second electric motor, and a second disconnect link. A control system is configured to detect a fault in the first portion, the second portion, or combinations thereof, and determine a response to the fault. In one example, on detection of the fault in the second portion, the second disconnect link is disengaged to reduce electromagnetic drag torque by the second electric motor.

Abstract: Aspects of the present disclosure involve an inverter employing switches of different types in parallel. In one example, an apparatus includes a voltage-source converter that may have a plurality of switch positions collectively coupled to convert an input to an output. At least one switch position may include a first switch of a first switch type and a second switch of a second switch type different from the first switch type. Also, the first and second switches may be coupled in parallel. The converter may also include a switch control circuit to generate, for each of the at least one of the switch positions, a first control signal to operate the first switch of the switch position, and a second control signal to operate the second switch of the switch position.
