    摘要: The present invention relates to an improved method for preparing an ethylene-silane copolymer comprising hydrolysable silane groups by radical-initiated polymerisation of ethylene and an olefinically unsaturated silane compound, such as vinyl trimethoxysilane (VTMS). Said method is performed in a multi-zone reactor comprising two or more reaction zones, wherein advantageously essentially all of the silane compound is introduced into the first reaction zone to provide a higher conversion of silane monomer into polymer.

    摘要: A turn-off power semiconductor component subdivided into unit cells (EZ), including between an anode (A) and a cathode (K) in a semiconductor substrate (1) five layers in p-n-p-n-p sequence, namely an anode layer (10) an n-type base layer (9), a p-type base layer (8), a turn-off region (6), a cathode region (7) adjoining the turn-off region, and a p-doped short-circuit region (5). On the cathode side in every unit cell (EZ), a first MOSFET (M1) which can be driven via a first insulated gate electrode (G1) is provided for the purpose of switching between the five-layer structure and a conventional thyristor four-layer structure. A second MOSFET (M2) having a second gate electrode (G2) prevents a breakdown between the p-type short-circuit region (5) and the turn-off region (6) during turn-off. p-Type short-circuit region (5), turn-off region (6) and cathode region (7) are introduced in a self-aligning manner into the semiconductor substrate (1) through the windows (F1, F2) between the gate electrodes (G 1 and G2, respectively). Current filamentation during turn-off is effectively avoided by the switchable five-layer structure. The self-aligning production makes possible a component having precise patterning.

    摘要: A high voltage AC transmission cable system for transmitting power between two points, each connected to one or more power networks, and a method to operate the system. At least one transformer is arranged at each end of the AC transmission cable, wherein at least one of the transformers is arranged to operate the transformer at a voltage whereby losses due to reactive power transport and dielectric losses are minimized. The AC cable is run at a variable voltage regulated such that the voltage is a function of the load for the transmission cable. This operating voltage is not necessarily the same as the nominal voltages in the connection points. A control and communication system and a graphical user interface for carrying out the method are also provided.
