Abstract: An electronic unit for a voltage converter of a rotating electric machine includes a first busbar including a first plate, a first connection portion projecting from the first plate, on a first side of the first plate. A first connection surface is able to be welded to a second connection surface of a third busbar of a power electronics module by a first laser weld using a first laser beam. A second busbar separate includes a second plate parallel to and located on a second side of the first plate, opposite the first side. The first or second busbar includes a first extension extending in line with the first connection surface, the first extension being able to block the first laser beam. A voltage converter can include the electronic unit, and the electrical assembly can include the voltage converter and a rotating electric machine.

Abstract: A cover for a rotating electric machine includes an axis of rotation (X), the cover being designed to be arranged on an inverter of the machine. The cover includes a skirt extending in a radial direction and forming a perimeter of the cover, the perimeter defining an inner portion of the cover and an open area arranged in the inner portion and comprising at least one axial opening. The open area extends over at least 50% of the inner portion of the cover.

Abstract: An electronic system includes a power electronics module for converting a DC current to an AC current. The power electronics module includes a first busbar and a second busbar for supplying the power electronics module with the DC current, a third busbar able to supply a phase winding of a rotating electric machine, and a control pin receiving a control signal for driving the power electronics module. An electronic control module separate from the power electronics module is configured so as to generate the control signal. The electronic control module includes an electronic measuring device, a support including an opening and carrying the electronic control module on a first side of the support, a measurement housing including a cavity, the measurement housing being located on a second side of the support opposite the first side of the support. The electronic measuring device penetrates into the opening in the support and into the cavity in the measurement housing.

Abstract: The voltage converter (104) comprises:—a power module (110) comprising at least one controllable switch intended to switch in order to perform a voltage conversion;—a heat sink (206) having an upper face opposite a lower face of the power module (110) for dissipating heat emitted by the power module (110); and—at least one resilient element (308) bearing on an upper face of the power module (110) in order to hold the power module (110) in place relative to the heat sink (206). Each resilient element (308) is rigidly connected to the heat sink (206).

Abstract: An electronic assembly for a rotary electric machine for a motor vehicle is disclosed. The electronic assembly includes electronic component blocks having different thermal dissipation needs, the blocks including a power block and a control block. The assembly also includes a device for cooling the blocks and having a protective cover suitable for covering the power and control blocks. The protective cover includes a first set of openings configured to be positioned opposite a first cooling element coupled to the power block, and opposite the control block, the first cooling element being a first dissipator provided with a base plate, the base plate protruding with respect to the power block to create a first radial flow of cooling air (F1) for the power block and a second radial flow of cooling air (F2) for the control block.
