Abstract

A three-phase switching unit including three identical switching cells, each including at least one first electrically-controlled switch in series with at least one second spontaneous conduction switch, wherein the cells are arranged, around a conductive central area of a substrate, with a symmetry of revolution of order 3.

First claim

What is claimed is:

1 . A three-phase switching unit comprising three identical switching cells, each comprising at least one first electrically-controlled switch in series with at least one second spontaneous conduction switch, wherein the cells are arranged, around a conductive central area of a substrate, with a symmetry of revolution of order 3.

2 . The unit of claim 1 , wherein the spontaneous conduction switches are assembled in the conductive central area with a symmetry of revolution of order 3.

3 . The unit of claim 1 , wherein the conductive central area supports no component.

4 . The unit of claim 1 , wherein the central area also has a symmetry of revolution of order 3.

5 . The unit of claim 1 , wherein the switch(es) of the switching cells are arranged on conductive peripheral areas of the substrate having a symmetry of revolution of order 3.

6 . The unit of claim 5 , wherein the central area and the peripheral areas approximately form a Y.

7 . The unit of claim 1 , wherein the conductive central area has a substantially hexagonal shape.

8 . The unit of claim 1 , wherein said first switch(es) are transistors.

9 . The unit of claim 1 , wherein said spontaneous conduction switch(es) are diodes (D) or MOS transistors.

10 . The unit of claim 1 , wherein each switch is welded to a conductive area by a back-side metallization of a chip made of semiconductor materials, defining an electrode of the switch.

11 . The unit of claim 1 , wherein the conductive central area defines a terminal of electric interconnection of the three cells.

12 . The unit of claim 1 , wherein the substrate is an insulated metal substrate, preferably on ceramic.

13 . A three-phase current inverter, comprising two units of claim 1 .

14 . The current inverter of claim 13 , wherein the cells of the two units are electrically connected two by two, the interconnection nodes defining three phase terminals.

15 . A system comprising:
an assembly of photovoltaic panels; and the inverter of claim 13 .
