Abstract: A subassembly for an electrical component includes: a first plate including: a wall, stepped walls extending from opposite sides of the wall, flange elements extending outwardly from the stepped walls, each flange element defining an engagement slot; a first heatsink positioned on the wall between the stepped walls; a second heatsink; a power module between the first heatsink and the second heatsink; and a second plate including: a plate wall extending across the second heatsink, transition walls extending from opposite sides of the plate wall, and prongs extending from the transition walls toward the first plate and substantially perpendicular to an inner surface of the plate wall in contact with the second heatsink, wherein the prongs are aligned with and configured to engage the engagement slots.

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.

Abstract: A mounting arrangement for a capacitor package is disclosed. The capacitor package is suitable for use in electric drive traction applications that are subjected to high vibration. Such a capacitor package is relatively large and requires a unique mounting arrangement in order to account for a large mass and high vibration environment. The mounting arrangement provides a clamp load plane that is near the center of mass of the capacitor package.

Abstract: A casting for a housing for a flexible, configurable power converter is disclosed. The housing includes a power compartment that is configured to accept a heat sink in either of two orientations. The configurable nature of the power converter allows the same power convertible package to be used in a number of applications without having to incur the cost of developing a new power converter package.

Abstract: An electric drivetrain using a configurable power converter package is disclosed. The configurable design allows for the power converter to support the drivetrain needs of a product line of machines without having to design a new power converter for each application. The electric drivetrain includes a first power conversion stage comprising a first configurable power converter and a second power conversion stage comprising a second configurable power converter. The first and second configurable power converters are one of a plurality of power configurations of a configurable power converter package.

Abstract: A configurable power converter package is disclosed. The configurable design allows for the power converter to support the drivetrain needs of a product line of machines without having to design a new power converter for each application. Major components of the power converter package such as the housing, heat sink, power modules, and bus bars are designed to be combined into a number of different power configurations. The power configurations fulfill the needs of a product line of electric drivetrains without the need to design a new power converter package for each application.
