Abstract:
Power inverters include a frame and a power module. The frame has a sidewall including an opening and defining a fluid passageway. The power module is coupled to the frame over the opening and includes a substrate, die, and an encasement. The substrate includes a first side, a second side, a center, an outer periphery, and an outer edge, and the first side of the substrate comprises a first outer layer including a metal material. The die are positioned in the substrate center and are coupled to the substrate first side. The encasement is molded over the outer periphery on the substrate first side, the substrate second side, and the substrate outer edge and around the die. The encasement, coupled to the substrate, forms a seal with the metal material. The second side of the substrate is positioned to directly contact a fluid flowing through the fluid passageway.
Abstract:
An attachment arrangement for a heat sink includes, but is not limited to, an attachment surface defined on the heat sink. A thermally conductive adhesive is disposed on the attachment surface. A substrate is attached to the attachment surface via the thermally conductive adhesive. The thermally conductive adhesive defines a discontinuity that is disposed in a delamination path of the thermally conductive adhesive.

Abstract:
An inverter assembly for a vehicle includes a housing, a first inverter, and a second inverter. The housing comprises a plurality of walls. The plurality of walls form an inlet for cooling fluid to enter the housing, an outlet for the cooling fluid to exit the housing, and a channel, and a channel for the cooling fluid to flow therebetween. The first inverter is disposed within the housing proximate the channel, and is configured to be cooled by the cooling fluid flowing through the channel. The second inverter is also disposed within the housing proximate the channel, and is also configured to be cooled by the cooling fluid flowing through the channel.
Abstract:
A power electronics assembly is provided. The assembly includes a housing defining at least one cavity and having a fluid passageway extending therethrough, the fluid passageway having first and second portions on respective first and second opposing sides of the at least one cavity, and a plurality of inductors housed within the at least one cavity of the housing such that the first and second portions of the fluid passageway are on first and second opposing sides of each of the plurality of inductors.
Abstract:
Systems and apparatus are provided for capacitor segments for use in a vehicle. A capacitor segment comprises an inner conductor configured to receive a first potential and having a generally L-shaped longitudinal cross-section. An outer conductor is configured to receive a second potential, and is electrically insulated from the inner conductor. The outer conductor comprises a first section having a generally L-shaped longitudinal cross-section aligned with the inner conductor, and a second section coupled to the first section and having a generally L-shaped lateral cross-section. The second section and the inner conductor define an inner region. A capacitor is located in the inner region and coupled to the inner conductor and the second section. The capacitor segment is configured such that current flows through the capacitor in a first direction, and current flows through the second section in a second direction that generally opposes the first direction.
