摘要:
A converter arrangement comprises a base structure (1), on which lines (2) of a first electrical network (3) are arranged. A plurality of first contacts (4) is also arranged on the base structure (1), which contacts can be transferred from a first connection position into a first release position by means of a first actuator (5). In the first release position, a converter assembly (6) can be secured as a unit in a receptacle (7) of the base structure (1) and can be removed from the receptacle (7). As long as it is secured in the receptacle (7) of the base structure (1), the converter assembly (6) is arranged immovably in the receptacle (7). The converter assembly is electrically connected to the lines (2) of the first network (3), if and whilst the first contacts (4) are in the first connection position. The converter assembly is electrically disconnected from the lines (2) of the first network (3), if and whilst the first contacts (4) are in the first release position. The receptacle (7) is not moved when the first contact (4) is transferred from the first connection position into the first release position.

The invention relates to an arrangement (1) which comprises at least one semiconductor module (2) and at least one electrical busbar (3). The semiconductor module comprises at least one substrate (6) and at least one semiconductor component (21, 22) arranged on said substrate and having at least one electrical contact (24) and at least one additional electrical contact (27). The busbar comprises at least one supply busbar (31) for providing a supply voltage for the contact of the semiconductor component. An electrical insulation film (7) is provided on the semiconductor component and/or on the supply busbar for electrically insulating the supply busbar from the additional contact of the semiconductor component. The contacts of the semiconductor component are contacted in a planar manner, the insulation film being used for the planar contact. The use of the insulation film eliminates the need for casting the semiconductor module with silicone, thereby obtaining a simple and compact design of the structure. The inventive arrangement is especially used for supplying power semiconductor components of power semiconductor modules. The power semiconductor modules are especially used in power converters.

The invention relates to a method for discharging an intermediate circuit converter (C zκ ) of an intermediate voltage circuit converter (2). The electronic power converter (4) of the intermediate voltage circuit converter on the line side has power semiconductors (A1,…,A6) that can be disconnected and can be connected to an AC supply network via a series connection of a precharging contactor (VS) and a precharging resistor (R v ), a transformer (T) and a main switch (HS) which series connection can be by-passed by means of a line contactor (NS). The main switch (HS) and the line contactor (NS) are opened, the precharging contactor (VS) being closed and two diagonally opposite disconnectible power semiconductors (A1, A4; A2, A3) of the electronic power converter (4) on the line side being connected. The invention devises a method for discharging an intermediate circuit capacitor (C zκ ) of an intermediate voltage circuit converter (2) without any additional components being required.

In summary, the invention relates to a busbar arrangement (1) for making electrical contact with at least one semiconductor module (2), wherein the busbar arrangement (1) has at least two busbars (11), wherein the busbars (11) are arranged in a mutually overlapping manner at least in an overlap region (13) of the busbar arrangement (1), wherein the busbars (11) are electrically insulated from one another, wherein the busbars (11) each have at least one web (20) with a connection element (21), wherein the webs (20) of the busbars (11) are arranged without an overlap. In order to reduce the interaction between the connections of the semiconductor module or of the semiconductor modules, it is proposed to orient the webs (20) in such a way that a first axis (31) can be formed, which first axis runs through the connection element (21) of the respective web (20) and to a point of a transition (19) of the respective web (20) to the overlap region (13) of the busbar arrangement (1), and which first axis intersects a second axis (32), which is formed by a connection of two connection elements (21) of the webs (20), at an angle of between 0° and 45°, wherein the busbars (11) each have an insulating region (14) which is arranged in such a way as to reduce or to prevent a current in the web (20) in a direction perpendicular to the second axis (32). The invention further relates to a converter module (3) comprising a busbar arrangement (1) of this kind.
