  • Patent number: 11431258
    Abstract: A power inverter has an inverter unit with a housing defining a main compartment and a first lateral compartment adjacent the main compartment. The main compartment contains an inverter power module configured to convert direct current (DC) power into alternating current (AC) power output, an inverter driver module configured to provide driving signals to drive the inverter power module, an inverter control module configured to provide control signals to the inverter driver module to control the AC power output, and a capacitor for coupling to the DC power. The capacitor is arranged on or over at least one of the inverter power module, the inverter driver module, or the inverter control module. Additionally, the power inverter has a base on which the housing sits, the base comprising a heat sink configured to draw heat away from one or more of the inverter power module, the inverter driver module, or the inverter control module.

  • Publication number: 20220190736
    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.

  • Patent number: 10843634
    Abstract: A cover for an operator console of a machine includes a first section rotatably coupled to the operator console. The first section selectively rotates between a first position and a second position about a rotational axis. The cover also includes a second section rotatably coupled to the operator console and the first section. The second section selectively rotates between a third position and a fourth position about the rotational axis. The second section is also adapted to engage with the first section during rotation of the second section from the third position to the fourth position to rotate the first section from the first position to the second position. The second section is further adapted to engage with the first section during rotation of the second section from the fourth position to the third position to rotate the first section from the second position to the first position.
