A power switching module is provided having at least one power switch placed above at least one other power switch, each power switch in turn including an upper wall and a lower wall, each of which is cooled through thermal conduction by a cooling medium that circulates in channels and voids that are provided along the walls for this purpose.

Power switching module and inverter equipped therewith

An electronic power device comprising support plates each having one face receiving one or more power components and an opposite face in contact with a cooling fluid for cooling said power components by conduction, wherein at least one support plate is associated with another support plate disposed facing it and provided with similar power components, and wherein the power components of the two facing support plates are disposed facing one another and in the immediate vicinity of one another.

Electronic power device

An electronic power device including at least one sub-system supporting power modules, a capacitor battery connectable to an electrical power supply and being connected to the power modules. The capacitor battery includes one or more capacitors which when a plurality are provided are disposed in parallel between first and second connection plates. Each sub-system has a first face supporting at least one first power module and a second face for supporting at least one second power module and wherein the first plate is connected to each first power module and the second plate is connected to each second power module.

Electronic power device and electronic power assembly comprising such a device

A cooling element (,) for power electronic devices comprises heat-exchange fluid inlet and outlet apparatus (,) and an interior volume in which said fluid circulates. The element (,) is made from an electrically insulative material and comprises at least one opening (,) connecting the internal volume (V) to the exterior of the element, a perimeter (,) of the at least one opening (,) forming a seat receiving at least one base (,A) of the power electronic device (,) to be cooled with sealing apparatus (,) between them. The element has a small volume compared to those of the prior art.
