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.
