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 multilevel power converter has at least one phase module with a plurality of modules (1_1 . . . 1_n; 2_1 . . . 2_n) connected between first and second DC voltage connections. The phase module has a first phase module branch connected to the first DC voltage connection, and a second phase module branch connected to the second DC voltage connection. Each of the modules has at least two electronic switching elements and an electric energy storage unit. A third phase module branch connects the first phase module branch to the second phase module branch. A switching device connects an AC voltage connection of the multilevel power converter to a first connection node between the first phase module branch and the third phase module branch in a first switch position and connects the AC voltage connection to a second connection node between the third phase module branch and the second phase module branch in a second switch position.

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： 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.
