    Abstract: The invention relates to a two-phase heat transfer device for dissipating heat from a heat source, for instance a power semiconductor module, by a heat transfer medium, wherein the two-phase heat transfer device includes a main body, wherein the main body is formed by a body material and includes a multi-dimensional void network, wherein the multi-dimensional void network includes voids and is adapted for containing the heat transfer medium, wherein the multi-dimensional void network is adapted such that a flow of the heat transfer medium along a path through the main body is based on a variation in capillary action exerted by the multi-dimensional void network on the heat transfer medium along the path. Further the invention relates to a power semiconductor module comprising the above two-phase heat transfer device for heat dissipation and to a method for producing the above two-phase heat transfer device.

    Abstract: Electrical contact system with a first and a second contact (1, 5), each having a contact surface (4, 8). The first electric contact (1) has a mesostructured electric contact portion (14) with a plurality of slots (15) and ridges (16) formed between neighboring slots (16) of the plurality of slots (16). These slots (15) and ridges (16) extend in a direction running transversely to said switching plane (X-Z) form a plurality of current paths (16). The current paths (16) are inclined to the first contact surface (4) at a first angle (17) measuring less than 60 degrees such that an interruption current (12) flowing through the mesostructured electric contact portion (14) and through an electric arc (11) extending in between the first contact surface (4) after lifting the first contact surface (4) off the second contact surface (8) pushes said electric arc (11) in the direction of the apex of said first angle (17) from a first position (18) to a second position (19).

    Abstract: An arrangement for charging of electric vehicles includes a charging connector and a charging cable. The connector includes a connector body with first and second zones, the two zones being separate from each other. The first zone hosts a mating interface with electrical contacts for mating the connector with a corresponding socket of an electric vehicle. The electrical contacts are electrically coupled to the cable. The second zone includes a tube in which the cable is guided from an opening of the tube, which is arranged on that side of the second zone that faces away from the first zone to the electrical contacts, which are located in the first zone, and a handle for grabbing the connector with a human hand, the handle being separate from the tube. The second zone is Y-shaped where the tube is formed by one upper leg and the lower of the Y.
