Definitions
- the present invention relates to an electronic power module, particularly for applications in fields such as automobiles, trucks, trains, photovoltaic systems, or battery management.
- one or more electronic power modules control the currents and voltages applied.
- a general desire to reduce carbon monoxide emissions supports the electrification of cars, buses and trucks.
- the electrification of mobility requires the construction of electric motors / generators and compact conversion systems. These machines and conversion systems most often include one or more remote or integrated electronic modules.
- Such a system most often comprises a control module and one or more electronic circuits consisting of active electronic components of the MOSFET or IGBT type arranged in a bridge.
- the power electronic components in the form of bare chips, are brazed on leadframes, which are overmolded in a mechatronic box. Or alternatively on ceramic substrates carrying copper tracks of the DBC type.
- These connection grids are maintained plated on a metal soleplate by means of an electrically insulating wafer which is sandwiched between the connection grids and the assembly substrate and the soleplate.
- the wafer has properties of good thermal conduction so as to transmit the calories generated by the chips to a heat sink placed under the metal sole of the circuit.
- FR2947679 is formed of an overmolded mechatronic housing:
- busbar intermediate connection traces and power traces, called "busbar" in English terminology, which are electrically connected to the electronic chips by soldered connection son.
- the present invention therefore aims at a design of an electronic power module overcoming these disadvantages.
- these electronic chips are mounted directly on the power traces formed at least in part of hollow metal profile segments having at least partially a flat outer surface.
- a first set of these power traces is electrically isolated from a second set of these power traces by at least a first substrate formed of a laminate comprising a first electrically insulating material and a second electrically conductive material.
- a cooling liquid circulates in these profiles.
- these profiles have according to the invention a rectangular cross section.
- the first material is an organic insulator and the second material is copper.
- the first substrate supports electronic control components of the electronic chips.
- the first set of power traces, the first substrate and the second set of power traces form a stack contained substantially in a parallelepiped volume.
- This stack further comprises, according to the invention, a second substrate below the first set of power traces and a third substrate above the second set of power traces forming at least one cavity containing an electrically insulating and thermally conductive liquid.
- the electronic chips are MOSFET or IGBT type power transistors inclusive of diodes forming branches of a bridge of an inverter intended to be connected as input to a power supply network of a power supply.
- motor vehicle and output to at least one winding of a rotating electrical machine of said vehicle.
- Figures 1a and 1b show schematically, respectively in side view and in top view, a power module according to the invention comprising a bridge of two-branch power transistors.
- Figure 2 shows in perspective an example of a concrete embodiment of a power module according to the invention similar to that shown schematically in Figures 1a and 1b. DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

- the electronic chip 2 in question corresponds to one of the transistors 2, 7, 8, 9 of a bridge of power transistors 2, 7, 8, 9 of MOSFET type with two branches:
- the first set of power traces 4, 5, 6 corresponds to so-called "low side” transistors 2, 7 whose sources are connected by the second element 6 to a first power connection terminal 10 of the module 1 intended to be connected to a ground, and to the connections 4, 5 of the drains of these "low side” transistors 2, 7 to the output terminals 1 1, 12 of the module 1 by the first element 4 and a third element 5;
- a second set of power traces 13, 14 corresponds to transistors 8, 9 called “high side", that is to say whose other drains are connected to a second power connection terminal 15 intended to be connected to a power supply of the module 1.
- the electronic chips of the transistors 2, 7, 8, 9 are mounted directly on the first set of power traces 4, 5, 6.
- the first and second sets of power tracks 4, 5, 6, 13, 14 are formed of segments of hollow rectangular section metal sections.
