摘要： A modular multilevel converter has a plurality of sub-modules, each of which includes at least two electronic switching elements and an electrical energy storage device. The sub-modules are controlled by a control device. An optical output of the control device of the converter is connected to an input of an optical distributor by way of a first optical waveguide. A plurality of outputs of the optical distributor are individually connected to an optical input of one of the sub-modules, respectively, by way of a second optical waveguide.

摘要： An alternating current circuit breaker has a series circuit of bipolar switching modules which are inserted in series into a phase line of an alternating current line. Each switching module has an energy storage device and actuatable power semiconductors that can be activated and deactivated. Each switching module can be driven such that a switching module voltage that corresponds to a positive or negative energy storage device voltage or a zero voltage can be generated at the poles of the switching module. A controller is configured to actuate the switching modules based on a polarity change of a phase current such that the switching module voltage switches polarity, wherein a switching module voltage opposite the phase voltage can be generated. A method for switching alternating currents is effected with the alternating current circuit breaker.

摘要： An electric energy storage device which is connected to an electronic circuit is discharged by way of a first and a second electric conductor. A thyristor is provided for discharging the energy storage device. As a result of a fault occurring in the electronic circuit, a discharge current of the energy storage device begins to flow from the energy storage device to the electronic circuit via the first electric conductor and back to the energy storage device via the second electric conductor. The discharge current causes a magnetic field which changes over time to be generated about the first electric conductor and the second electric conductor. The magnetic field penetrates the semiconductor material of the thyristor. By virtue of the temporally varying magnetic field, a current is induced in the semiconductor material of the thyristor, and the thyristor is activated by the induced current.

摘要： A submodule for a modular multistage converter contains a first and a second connection terminal, an energy store, and a power semiconductor circuit which is connected to the energy store such that the voltage dropping at the energy store can be generated at the connection terminals in a first switch state and a zero voltage can be generated at the connection terminals in a second switch state. The aim is to provide such a submodule which allows an inexpensive submodule housing to be used while maintaining the same energy storage capacity or which allows an increased energy storage capacity while using the same housing without thereby undermining the protection provided by the submodule housing. This is achieved in that the power semiconductor circuit is connected in parallel to an energy storage branch in which the energy store and a device for limiting a surge current are arranged.

摘要： A supply device supplies electrical power to an electrical assembly at a high-voltage potential. The supply device has a series circuit composed of at least one series resistor and a supply unit. The series circuit can be connected to an energy store and the supply unit can be connected to the assembly that is to be supplied with power. The supply device further has a fuse element, by which a short-circuit current through the supply unit can be electrically interrupted in the event of a short circuit.

摘要： A voltage-regulated power converter module includes an electrical charge storage device and a semiconductor switch connected thereto and having a collector, a gate and an emitter, in which the collector-emitter path of the semiconductor switch is switched into a current path between first and second alternating-current terminals of the power converter module. The alternating-current terminals can be interconnected through a bypass switch. The voltage-regulated power converter module is intended to minimize the occurrence of damage in the event of a fault, and allow the multilevel power converter to continue operating without possibly having to use an extremely fast bypass switch for this purpose. To this end, the collector and the gate of the semiconductor switch are interconnected through a circuit configuration, which is configured in such a way that it becomes conductive above a predefined voltage threshold. A power converter is also provided.
