A heatsink or heat exchanger for one or more power modules of an inverter or a converter comprises a coolant flow channel, comprised of a plurality of coolant flow channel portions that form a switchback or serpentine flow path, and that is adapted to circulate coolant inside the heat exchanger or heatsink. One or more vents can be provided inside the heat exchanger or heatsink to pass air from one coolant flow channel portion to an adjacent coolant flow channel portion.

Heatsink configuration and arrangment for inverter and systems, components, and methods thereof

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.

Modular configurable inverter and systems, components, and methods thereof

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.
