Abstract: An alternator includes a stator S, a rotor R and a transistor bridge, which form synchronous rectification. The synchronous rectification is in the form of an over-molded mechatronic housing (2), and the mechatronic housing includes an electronic power substrate (3) and power connection terminals (23), (24). Electronic chips (300A, 300B) are implanted on the electronic power substrate, and at least one of the power connection terminals is connected electrically to the electronic chip by means of at least a first soldered connection wire (300, 301, 302, 30B+, 30B?). According to one embodiment, the electronic power substrate is of the IMS, DBC or PCB type.

The synchronous rectification is in the form of an over-moulded mecatronic housing (2). The mecatronic housing includes power connection terminals (23, 24), and contains a plurality of electronic power substrates (30, 31, 32) which have the same architecture, and in each of which there is implanted at least a first electronic chip (300A, 300B) of the transistor bridge. According to one embodiment, the electronic power substrate is of the IMS, DBC or PCB type.
