Abstract: An assembly of electronic components for a rotary electrical machine and power and signal interconnection pieces cooperating with the electronic components in order respectively to distribute power to the electronic components and convey control signals between electronic components for the functioning of the rotary electrical machine, wherein the electronic components are disposed in at least one module disposed on a first plane, the at least one module comprising a housing defined by a top face and a bottom face and at least three lateral faces, the signal interconnection piece is disposed on a second plane parallel to the first plane, and the power interconnection piece is disposed on a third plane parallel to the first plane, the power and signal interconnection pieces being independent of each other and independent of the at least one module.

Abstract: A dissipator for electronic components, the electronic components being intended for the functioning of a rotary electrical machine, the machine comprising a rear bearing, the dissipator comprising a top face and a bottom face including fins. The present invention applies to any type of polyphase rotary electrical machine, synchronous or asynchronous, such as alternators or alternator starters, and also whether it is a case of electrical machines for motor vehicles and driven for example by belt, with cooling by air, liquid or any other solution that can be envisaged.

Abstract: This electronic module comprises a metallic base (12) and electronic power components (D1, D2, D3, D4, D5, D6) on the base; in which each component, in a group consisting of some of the components, is mounted on the base with a respective electrically insulating and thermally conductive element (44) being interposed, the other components of the power module being connected electrically to the said base, and in which a peripheral frame (14) is mounted on the base and incorporates interconnecting elements of electrically conductive materials. The invention is applicable in the field of motor vehicle alternators.
