An electrical filtering system including capacitors and an electrical distribution device including a stack of two electrically conducting layers facing one another and separated by an insulating layer, the stack being mounted on a rigid insulating plate, and said capacitors being mounted on said distribution device, the rigid plate extending in a plane orthogonal to the direction in which the layers are stacked. The distribution device includes a plurality of electrical connections distributed angularly over the outer perimeter of the distribution device and protruding in a plane parallel to the plane in which the rigid plate extends, and extending from the outer perimeter of the distribution device, each of the connections being, on the one hand, connected to at least one capacitor and, on the other hand, intended to be connected to an arm of an electrical inverter mounted on a tubular electrical converter of an electronic control unit.

Electrical filtering system for a smart electric motor with decoupled multiple windings and associated smart electric motor

An electric circuit for a power converter having a substrate having a first face on which electronic components are mounted and a second face intended to cooperate with a cooling system, the substrate having a stack of conductive layers made of electrically and thermally conductive material and at least one insulating layer made of electrically insulating material, two successive conductive layers being separated by an insulating layer, and the conductive and insulating layers extending in parallel planes and being mechanically associated together. Each conductive layer has two opposite faces parallel to the plane in which the first face of the substrate extends and includes, on at least one of its two faces, at least one boss extending in a direction perpendicular to the plane, the at least one boss passing through at least one other conductive layer and opening out onto the first or the second face of the substrate.
