Definitions
- the invention generally relates to the field of power electronics. More particularly, the invention relates to power switching modules and power electronic devices incorporating such modules.
- Power electronic devices such as inverters and power converters, but not exclusively, are very present in many fields of activity such as transport, industry, lighting, heating, etc. With the desired energy transition towards renewable and less carbon-intensive energy sources, power electronics will become more widespread and will have to respond to increasing economic and technological constraints. Current research and developments in the field of electronic power devices focus on reducing costs, increasing power density for more compactness, increasing reliability, reducing parasitic elements and radiation. electromagnetic and thermal transfer of dissipated energy. [004] The various constraints applying to electronic power devices have led to a modular architecture of switching bridges, with elementary power switching modules, called "power modules", each corresponding to a switching branch of the bridge. Thus, for example, a three-phase, hexaphase switching bridge, or comprising any number of phases or poles, can be obtained by assembling several power modules.
- power modules elementary power switching modules
- 3D architectures are proposed for power modules, with double-sided cooling power chips, and have a certain interest in increasing the compactness of electronic power devices.
- the search for greater compactness requires being able to keep the temperatures of active and passive components below critical values, to achieve thermal equilibrium and to ensure reliability. Extraction of the dissipated energy closer to the components is desirable.
- the thermal path between heat sources consisting of components and heat sinks consisting of heat dissipation means shall be optimized. Powerful cooling devices are therefore essential.
- the reduction of resistive, inductive and capacitive parasitic elements is essential to achieve the best possible compromise between the search for compactness and the satisfaction of the various design constraints.
- the parasitic inductances in the power bus buses oppose higher switching frequencies. Higher switching frequencies are favorable for compactness but increase switching losses and the power dissipated by the components.
- the reduction of parasitic inductances is necessary to protect the circuits against potentially destructive overvoltages, to improve the control of the electromagnetic radiations, to reduce the heat generated and to increase the switching speed.
- press-pack For the improvement of reliability, particularly in applications where thermal cycles are severe, so-called "press-pack” technology is used.
- press-pack technology electrical contacts are provided by mechanical pressure or clamping means that hold the components in place and in contact.
- the "press-pack” technology makes the power modules themselves modular and their submodules testable and replaceable. This results in more standardization and lower production costs.
- the "press-pack” technology also has the advantage of facilitating the repair of devices because of the dismountability thereof.
- the invention relates to a power module comprising an electronic card in which is integrated at least one power switching branch, a capacitor and at least three DC power supply buses, in which which the electronic card is mounted between a first busbar and a second busbar and the capacitor is mounted between the second busbar and a third bus bar and the electronic card, the capacitor and the busbar comprise electrical contact faces allowing a mounting of the type called "press pack" of the electronic card and the capacitor.
- the power module has an outer shape which is contained in a cylindrical sector having a determined angle and the electrical contact faces are substantially perpendicular to a radial plane of symmetry of the cylindrical sector.
- the capacitor is of the multilayer ceramic type.
- the electronic card is of the so-called “SiP” type and comprises control means and at least one capacitive first level capacitive filtering capacitor.
- the first-level capacitive filtering capacitor is a multilayer ceramic capacitor.
- the first busbar comprises an outer arcuate surface comprising a plurality of cooling fins.
- At least the first bus bar among the three bus bars comprises two junction faces inclined symmetrically with respect to the radial plane of symmetry.
- At least one passage channel and / or filling for a liquid having a heat-transfer function and / or fireproofing and / or electrical insulation is included in at least one of the three buses. bars.
- At least one power switching branch comprises at least one type of transistor GaN, SiC, MOSFET or IGBT.
- the three bus DC power bus buses are copper and / or aluminum.
- the invention also relates to an electronic power device comprising a plurality of power modules as briefly described above, the power modules being arranged in a circle and being in electrical contact by their first, second and third bus bars.
- the electronic power device comprises a central volume occupied by a liquid and / or an electrical, mechanical and / or electronic element, the liquid having a heat-transfer function and / or fireproofing and / or electrical insulation.

- the capacitive filtering means comprise a first capacitor Ci and a second capacitor CE which are connected between the bus + DC and -DC.
- the capacitors Ci and CE respectively form a first level capacitive filtering means and a second level capacitive filtering means.
- the switching bridge branch BM, the controller pC and the capacitor Ci are included in the same electronic card EB of the SiP type.
- the capacitor Ci is typically of the multilayer ceramic type and may be formed of a single capacitor or of several capacitors in parallel. By being implanted in the electronic card CE, the capacitor Ci, as capacitive filtering means of first level, is located closer to the chips of the transistors. [0030]
- the electronic card CE may be formed with proven and economical techniques for manufacturing printed circuit boards and have a 3D architecture.
- the capacitor CE as second level capacitive filtering means, has a capacity much greater than that of the capacitor Ci and thus provides a larger capacitive filtering.

- a volume E3 is available in the cylindrical sector SC between the sector axis AA and the face F9.
- channels 13 visible in Fig.2, which are provided on the upper and lower end faces of the bus bar B3.
- the channels 13 are intended in particular for the passage, or filling, of the coolant and / or fireproof and / or electrical insulation.
- the assembly "press-pack" of the power module 1 will use, for example, elastic fasteners ensuring the required clamping or screws mounted through insulated screw passages to avoid short circuits. These clamping mechanical assembly techniques are well known to those skilled in the art and are not detailed here.
- a central volume VC remains available by adding the different volumes E3 left free.
- the central volume VC may be dedicated to different functions.
- the central volume VC may be dedicated, partially or completely, to the circulation or filling of a liquid having a function of heat transfer and / or fireproofing and / or electrical insulation.
