A power semiconductor module, and an arrangement using the module. The module has a basic parallelepipedal shape with opposed pairs of main, longitudinal and narrow sides, a cooling device which is capable of carrying a flow of a cooling fluid, having a power electronics switch and a housing. The cooling device has a cooling volume with at least one cooling face and four connection devices which are arranged in pairs on the main sides. In addition, the connection devices carry the cooling fluid and are designed as a flow inflow and a flow outflow and as a return inflow and a return outflow, respectively. The power electronics switch has load input connection devices and load output connection devices which are arranged on one or both longitudinal sides and a control connection device which is arranged on a narrow side of the module.

Modular liquid-cooled power semiconductor module, and arrangement therewith

An arrangement having a cooling circulation, a plurality of modular power semiconductor modules and at least one capacitor, wherein a power semiconductor module has a power electronics switch and a cooling device, which is capable of carrying a flow of a cooling fluid, for cooling the switch, the cooling device having at least one cooling face, and four connection devices for the cooling fluid. The connection devices are arranged in pairs on main sides of the power semiconductor module. The power semiconductor modules have their main sides strung together modularly by connecting corresponding connection devices on successive power semiconductor modules. To this end, at least two successive power semiconductor modules have a capacitor arranged between them which, for its part, is cooled by means of the cooling circulation of the cooling fluid as provided by the arrangement.

Liquid-cooled arrangement having modular power semiconductor modules and at least one capacitor device, and power semiconductor module therefor

A method for making a power semiconductor module and a module produced by that method, wherein the module includes a substrate, a connection device and load terminal elements, wherein power semiconductor components are arranged on a conductor track of the substrate and connected to one of the load terminal element by the connection device. The power semiconductor module has auxiliary contact pads which can be connected to an external printed circuit board. The primary production step in this case is cohesively connecting respective first contact areas of the first conductor tracks to at least one second contact area of a power semiconductor component and at least one third contact area of a load terminal element; afterwards, the assemblage composed of at least one power semiconductor component of a connection device and load terminal elements is arranged to form a housing of the power semiconductor module.

Method for producing a power semiconductor module, and power semiconductor module comprising a connection device

A power semiconductor module comprises at least one power semiconductor component and a connection device which makes contact with the power semiconductor component. The connection device is composed of a layer assembly having at least one first electrically conductive layer facing the power semiconductor component and forming at least one first conductor track, and an insulating layer following in the layer assembly, and a second layer following further in the layer assembly and forming at least one second conductor track, the second layer being remote from the power semiconductor component. The power semiconductor module has at least one internal connection element, wherein the internal connection element is embodied as a contact spring having a first and a second contact section and a resilient section. The first contact section has a common contact area with a first or a second conductor track of the connection device.

Power semiconductor module comprising a connection device with internal contact spring connection elements

A power semiconductor module having a housing, a substrate with conductor tracks and power semiconductor components arranged on the conductor tracks, and a connecting device. The connecting device comprises a film composite with first and second conductive layers, which are respectively patterned and thus form conductor tracks, and an insulating layer disposed between the two conductive layers. The first conductive layer has first contacts, formed as spot-welded joints, for power connecting areas of power semiconductor components, second contacts for control connecting areas of power semiconductor components and third contacts for the load connection to a printed circuit board. The second conductive layer connects to the first conductive layer and fourth contacts for providing control connection to an external printed circuit board. The film composite also has film sections between the first and second contacts and between the third and fourth contacts, which are arranged in guide sections of the housing.
