Abstract

The subject of the invention is an electronic architecture ( 10 ) intended to supply an electric machine for automotive vehicle, the electronic architecture ( 10 ) comprising at least:
an electronic power unit ( 100 ); a thermal dissipator ( 200 ) supporting the electronic power unit ( 100 ); an electronic control unit ( 300 ) configured to control the said electronic power unit ( 100 ); a support ( 400 ) of the electronic control unit supporting the electronic control unit ( 300 ) and arranged between the electronic power unit ( 100 ) and the electronic control unit ( 300 ); and an electrical connector ( 500 ) comprising at least one power trace intended to be connected electrically to at least some electrical elements (phase φ, B + , B − ) of the electric machine and/or of an electrical energy source, the electrical connector ( 500 ) being arranged between the electronic power unit ( 100 ) and the support ( 400 ) of the electronic control unit and configured to electrically connect the electronic power unit ( 100 ) and/or the electronic control unit ( 300 ) to the at least one power trace.

First claim

The invention claimed is:

1. An electronic architecture for supplying an electric machine for automotive vehicle, the electronic architecture comprising:
an electronic power unit;
a thermal dissipator supporting the electronic power unit;
an electronic control unit configured to control the said electronic power unit;
a support of the electronic control unit supporting the electronic control unit and arranged between the electronic power unit and the electronic control unit; and
an electrical connector comprising at least one power trace that connects electrically to at least some electrical elements of the electric machine and/or of an electrical energy source, the electrical connector being arranged between the electronic power unit and the support of the electronic control unit and electrically connecting the electronic power unit and/or the electronic control unit to the at least one power trace,
in which the electronic power unit, the thermal dissipator, the electrical connector, the electronic control unit and the support of the electronic control unit each extend along substantially parallel planes, the electronic power unit, the thermal dissipator and the electrical connector being superposed one above the other, and
in which the electrical connector further comprises:
a first power trace that electrically connects the electronic power unit to a phase of the electric machine;
a second power trace that is connected electrically to a positive polarity pole of an electrical energy source so as to supply the electronic power unit and/or the electronic control unit; and
a third power trace that is connected electrically to a negative polarity pole or to the earth of an electrical energy source so as to supply the electronic power unit and/or the electronic control unit.

2. The electronic architecture according to claim 1 , furthermore comprising:
at least one electrical connection element electrically connecting the electronic power unit and the electronic control unit,
wherein at least one space extends between the electronic power unit and the support of the electronic control unit and around the at least one electrical connection element, the electrical connector extending at least in part in the said space around the electrical connection element.

3. The electronic architecture according to claim 2 , in which the electronic power unit, the electronic control unit and the at least one electrical connection element are embedded in an insulating material, so that the at least one space extending around the at least one electrical connection element between the electronic power unit and the support of the electronic control unit is devoid of insulating material.

4. The electronic architecture according to claim 1 , further comprising a capacitor bank connector supported by a second part of the thermal dissipator distinct from a first part supporting the electronic power unit.

5. The electronic architecture according to claim 4 , in which the first part of the thermal dissipator is intended to be filled with an insulating material, so that the electronic power unit is embedded in the insulating material.

6. The electronic architecture according to claim 1 , also comprising a protective cover arranged opposite the electronic control unit.

7. The electronic architecture according to claim 1 , in which:
the electronic power unit comprises at least one electronic power module; and
the electronic control unit is an electronic control board.

8. The electric machine configured to be integrated into an automotive vehicle, comprising an electronic architecture according to claim 1 .
