  • Potential equalization system for a modular multilevel converter
    Patent number: 11081972
    Abstract: 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.
    Type: Grant

  • Electrical device having a semiconductor circuit
    Patent number: 11063524
    Abstract: An electrical device with a semiconductor circuit that is configured for a high voltage and is arranged in a housing. The housing is formed of a plurality of housing parts which are electrically insulated from one another. Different electrical potentials can be assigned to the housing parts. There is also described an converter with the electrical device.
