  • Publication number: 20230387789
    Abstract: An inverter system is provided such that the system includes a direct-current (DC) voltage supply, an inverter, an electric machine such as a motor, and a controller coupled with the inverter. The inverter has four or more legs, each with two switches operating complementary to each other. The controller can determine which three of the four or more legs are selected to operate the inverter and uses a remaining one of the four or more legs to operate the inverter by activating/deactivating certain switches during null vector state.

  • Publication number: 20230182585
    Abstract: The present disclosure generally relates to systems and methods for implementing power a power split between a first and a second power source in a fuel cell powertrain system. The method includes receiving an input into a processor of the fuel cell powertrain system, determining an output by the processor, communicating the output by the processor to a system controller and determining a power split by the system controller. The first power source includes a fuel cell system and the second power source is selected from a battery system or an engine, and the input includes a life or health of at least one of the first power source or the second power source.

  • Patent number: 11597287
    Abstract: Vehicles that are capable of connecting to the AC grid are described that comprise a prime mover and at least one motor generator. In one embodiment, a vehicle may be constructed as a plug-in hybrid system and using the powertrain under controller instruction to either place power on an AC power line (to service AC grids) or to draw power from the AC power line to add electrical energy to the batteries on the vehicle. In some aspects, vehicles may test whether the power needed to service the AC power line may be satisfied by the on-vehicle batteries or, if not, whether and how much power to extract from the prime mover. In some aspects, vehicles may have a thermal management system on board to dynamically supply desired heat dissipation for the powertrain, if the powertrain is using the prime mover to supply power to the AC grid.
