20100089641 | LOW INDUCTANCE BUSBAR - A busbar assembly for an inverter module has a power module, a capacitor module with at least one capacitor, and a battery all interconnected by a busbar. The busbar includes a base busbar portion that is electrically coupled to the battery and a branch busbar portion that extends from the base busbar to the power module and that electrically connects to the capacitor module at points located between the base node and the power module. | 04-15-2010 |
20110067841 | HEAT SINK SYSTEMS AND DEVICES - A heat sink is provided for that eliminates inefficient coolant bypass channels. The heat sink comprises a coolant cavity that is defined by a cover and a body portion. The thermally conductive cover includes a first plurality of substantially uniformly dispersed pin fins that extend at an angle from the inside surface of the cover towards a section of the body portion that is opposite the cover. The body portion opposite the cover includes a second plurality of pin fins that extend in the opposite direction from the first plurality. The coolant cavity also includes thermal bosses that protrude from an inside surface of the body portion. The bosses run parallel to the first and second plurality of pin fins and extend from a point near the thermally conductive cover to the section of the thermally conductive body portion that is opposite to the thermally conductive cover. | 03-24-2011 |
20110096496 | POWER ELECTRONICS ASSEMBLY WITH MULTI-SIDED INDUCTOR COOLING - 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. | 04-28-2011 |
20140168900 | SCALABLE AND MODULAR APPROACH FOR POWER ELECTRONIC BUILDING BLOCK DESIGN IN AUTOMOTIVE APPLICATIONS - A power electronic building block includes a housing; a power module mounted within the housing; a controller mounted within the housing and coupled to the power module; a capacitor assembly coupled to the power module and mounted within the housing; an AC bus bar mounted within the housing; and a DC bus bar coupling the capacitor assembly to the power module and mounted within the housing. | 06-19-2014 |
20140202279 | TRANSMISSION FOR A VEHICLE - A transmission for a vehicle is disclosed. The transmission includes a casing. The casing includes a base and a plurality of walls extending outwardly away from the base to a distal edge. The casing defines a first cavity and a second cavity between the walls. The transmission also includes a platform disposed between the walls to separate the first and second cavities. The first cavity is disposed adjacent to the distal edge of each of the walls. The transmission further includes a power inverter module defining a self-contained unit selectively disposed in the first cavity. The self-contained unit is supported by the platform when in the first cavity. | 07-24-2014 |
20140202402 | TRANSMISSION FOR A VEHICLE - A transmission for a vehicle is disclosed. The transmission includes a casing defining a first cavity and a second cavity inside the casing, with the first cavity selectively open to outside of the casing. The transmission also includes a platform at least partially disposed inside the casing to separate the first and second cavities. Furthermore, the transmission includes a power inverter module selectively disposed in the first cavity. The power inverter module includes a cooling system for cooling the power inverter module. The transmission also includes a guide attached to the platform and the casing within the second cavity such that the guide provides fluid communication between the cooling system of the power inverter module within the first cavity and outside of the casing while bypassing the second cavity. | 07-24-2014 |
20140203676 | TRANSMISSION FOR A VEHICLE - A transmission for a vehicle is disclosed which includes a casing defining a first cavity and a second cavity inside the casing. A platform is at least partially disposed inside the casing to separate the first and second cavities. The platform defines a plurality of first apertures arranged together to define a first group. An interface assembly includes a first support and a plurality of first connectors attached to the first support to define a first bundle. The first support is selectively attached to the platform to position the first bundle relative to the platform such that each of the first connectors are disposed in respective ones of the first apertures of the first group. The first connectors are coupled to a power inverter module and a first motor/generator through the first apertures of the platform to electrically connect the power inverter module and the first motor/generator to each other. | 07-24-2014 |
20140204555 | ELECTROMAGNETIC INTERFERENCE REDUCTION ASSEMBLY FOR A TRANSMISSION OF A VEHICLE - An electromagnetic interference reduction assembly for a transmission is disclosed. A transmission casing includes a base and walls extending outwardly away from the base to a distal edge. The transmission casing defines a first cavity between the walls and includes a platform disposed between the walls. A power inverter module is disposed in the first cavity and supported by the platform when in the first cavity. The power inverter module generates electrical noise during operation which produces electromagnetic interference. A lid is attached to the distal edge of the walls to contain the power inverter module inside the first cavity. A grounding member engages the power inverter module and the lid when the lid is attached to the transmission casing to electrically connect the power inverter module to the lid to reduce the electrical noise exiting the first cavity which reduces the electromagnetic interference exiting the first cavity. | 07-24-2014 |
