摘要： A method for operating a controllable electrical device connected by a data link to a control device for controlling the electrical device, includes using the electrical device to exchange electrical power with a connected electrical grid and using an environmental sensor for collecting environmental information. The control device transmits control signals to the electrical device over the data link. The electrical device assumes a first or a second operating state depending on the control signals transmitted. The electrical device exchanges energy with the electrical grid in the first operating state and the electrical device does not exchange energy with the electrical grid in the second operating state. Environmental information collected by the environmental sensor is transmitted over the data link to the control device only when the electrical device is in the second operating state. An assembly for carrying out the method is also provided.

摘要： A power module for a converter, in particular for a multilevel converter. The power module includes a link circuit capacitor, two connection terminals, at least one half-bridge connected in parallel with the link circuit capacitor and having two semiconductor switches, and, for each half-bridge, a bypass diode connected in parallel with a first semiconductor switch of the half-bridge and a load-relief circuit group connected in parallel with the first semiconductor switch. The load-relief circuit group has a load-relief thyristor and a load-relief diode connected in series with the load-relief thyristor.

摘要： An electrical configuration contains at least one submodule which has a first and a second outer electrical terminal. The configuration further has a bypass switching device, which is electrically connected between the first and second terminals and in the on-state causes an electrical short-circuit in at least one current flow direction between the two outer terminals. The bypass switching device has a thyristor with an anode terminal, a cathode terminal and a trigger terminal and is connected by its anode terminal to one of the two outer terminals and by its cathode terminal to the other of the two outer terminals. A triggering device is connected to the trigger terminal of the thyristor for triggering the thyristor, and a switch is provided which in the on-state connects the anode terminal of the thyristor to the trigger terminal of the thyristor.

摘要： A potential equalization system for a modular multi-level converter. The converter has a plurality of converter modules and each of the modules has a direct current source. The potential equalization system includes pole contacts, which are each electrically connected to one pole of a direct current source, and at least one electrically conductive contacting element, which can be moved between a first end position in which the contacting element is electrically isolated from the converter modules and a second end position in which the contacting element contacts pole contacts of different direct current sources and can be put on ground potential.
