  • Modular configurable inverter and systems, components, and methods thereof
    Patent number: 11515802
    Abstract: A modular inverter arrangement comprising one or more cages of a cage assembly, including at least a first cage of the cage assembly. Each of the one or more cages can be in the form of a cuboid, and each of the one or more cages can be adapted to accommodate therein respective sets of one or more power modules. The modular inverter arrangement can also be comprised of a heatsink extending transversely through each of the one or more cages, from a first end of the cage assembly to a second end of the cage assembly opposite the first end.
    Type: Grant
    Filed: December 15, 2020
    Date of Patent: November 29, 2022
    Assignee: Caterpillar Inc.
    Inventors: Paul T. Schmidt, Josh W. Dorothy, Kyle A. Halfacre, Zachary W. Newell, Johnson David Sugidharan Lawrence, Saravanan Desigan

  • Power inverter with balanced power flow for multiple electrical machines
    Patent number: 10064302
    Abstract: A power inverter assembly provides a balanced power flow to each of a plurality of electrical machines. The power inverter assembly includes at least one heat sink having a top side and a bottom side, a plurality of pairs of power semiconductor modules mounted along the top and bottom sides of a heat sink for thermal exchange with the heat sink, and a plurality of gate driver boards configured to control the supply of DC power to each of the plurality of pairs of power semiconductor modules. A first pair of semiconductor modules is symmetrically arranged relative to second and third pairs such that the arrangement of the first, second, and third pairs of power semiconductor modules forms a geometric pattern with at least one of the second and third pairs at least partially overhanging the first pair.
