Abstract: A converter has a network-side and a load-side power converter that are connected together on the DC side in an electrically conductive manner. An upper and a lower valve branch of each phase module, respectively, of the load-side power converter has at least one two-poled subsystem. At least one multiphase network-controlled power converter is provided as the network-side power converter. In this way, a converter is obtained, in particular an intermediate voltage circuit converter for intermediate voltages, which combines a simple and cost-effective feed circuit on the network side with a modular multilevel converter on the load side.

Abstract: The invention relates to a method for controlling a power converter having at least two phase modules, which each have an upper and a lower valve branch, each having at least three series-connected two-pole subsystems, in the event of failure of at least one subsystem of a valve branch of a phase module. According to the invention, the valve branch (TI, T6) with the failed subsystem (10) is determined, and in each case a subsystem (10) of a valve branch (TI, T6), which corresponds to the faulty valve branch (TI, T6), of any fault-free phase module (100) is driven such that its terminal voltages (UX21) are in each case zero. A polyphase power converter with distributed energy stores (9) is therefore operated with redundancy.

According to the invention, a protection component (12) is connected in parallel to the connector contacts (X1, X2) of each subsystem (10). A rectifier circuit is thus obtained with distributed energy stores which can be operated redundantly in case of fault.

Abstract: Method and apparatus for controlling a turn-off power converter valve having at least two series connections. Each non-latching power semiconductor switch of this power converter valve has an active collector-emitter limiting circuit. When a rising edge of a drive signal that is provided arrives, a predetermined value of the reference limited voltage of the active collector-emitter limiting circuit is decreased to a low value and is increased to the predetermined value again during a turn-off operation. Using a switch-on command, it is possible to balance the voltage sharing on the non-latching power semiconductor switches of a turn-off power converter valve having at least two series connections.

Abstract: Method and device for controlling a process in a vehicle, in particular for controlling a drive in the vehicle, using at least one processor. Control functions are stored in the form of program code in a processor-addressable address space of at least one memory. The address space is divided into segments of equal length, and the program code is stored as program parts per control function in individual, consecutive sections in the segment. At least two segments are linked so that a section of a first segment is programmed as an exit label from the first segment, and a second section in the second segment is programmed as an entry label to the second segment. A transition from the exit label of the first segment to the entry label of the second segment brackets the code segments and thus expands the possible segment area.

Thus, the data record is switched as a function of the engine bank.

Abstract: In a control device (14) for fuel injection and/or spark ignition in an internal combustion engine, a first datablock (16) is programmed for operation in accordance with engine operating parameters (BM, P, L, n, T) but without lambda control when the engine is cold and a second datablock (18) is programmed for operation with lambda control when the engine is warm. A switching logic (26) switches in the first datablock (16) when the engine is started below a lower threshold (T.sub.1) and switches over to the second datablock (18) when the temperature rises above a higher threshold (T.sub.2).
