  • Publication number: 20210359615
    Abstract: A converter arrangement has a line-commutated converter with an AC voltage terminal to be connected to an AC voltage grid via at least one phase line. The converter arrangement has at least one switching module branch that is arranged in series in the at least one phase line and that includes a series connection of switching modules at whose terminals bipolar voltages that sum to give a branch voltage are in each case able to be generated. A bypass branch is arranged in a parallel connection to the switching module branch. At least one switching device is arranged in the bypass branch. The switching device includes activatable semiconductor switches that are connected in antiparallel. There is also described a method for starting up the converter arrangement.

  • Patent number: 11096483
    Abstract: A household appliance, in particular a refrigerator or a freezer or a furniture item comprising at least one storage space, in which a support plate is positioned comprising a storage area and a shelf which can be rotationally and translationally moved on the storage area of the support plate, wherein: the shelf comprises a flat storage area which is oriented plane-parallel to the storage area of the support element; the shelf can be rotated relative to the support plate in a first rotational direction and can be displaced in a predefined direction; mutually facing bearing surfaces of the storage areas each have closed peripheral raceway grooves in which rolling elements are guided; the raceway grooves are formed such that, when a force is applied to the shelf in a direction defined in the plane of the storage area, the shelf can be moved, in a movement which is at least partially forcibly guided and which is simultaneously rotational and translational, from a base position into an intermediary position, the

  • Patent number: 11098758
    Abstract: A device for rotationally and translationally moving an object comprising a flat storage area relative to a storage area of a support plate arranged plane-parallel to the storage area, wherein: the object can be rotated relative to the support plate in one of two possible opposing rotational directions and can be displaced in a predefined direction; mutually facing bearing surfaces of the storage areas each have closed peripheral raceway grooves in which rolling elements are guided; the raceway grooves are formed such that, when a force is applied to the object in a direction defined in the plane of the storage area, the object can be moved, in a movement which is at least partially forcibly guided and which is simultaneously rotational and translational, from a starting position into an intermediary position, the object being rotated relative to the support plate in one of two possible opposing rotational directions and being displaced in a predefined direction; and the object, after being moved into the int

  • Publication number: 20210227974
    Abstract: A storage shelf base for an item of furniture or household appliance has a support plate stationarily arranged on a body of the item of furniture or household appliance, and a storage shelf which is positively driven relative to the support plate and can simultaneously be moved rotationally and translationally. Facing bearing surfaces of the support plate and the storage shelf have respective at least substantially closed circulating running grooves, in which rolling elements are guided. The support plate can be detachably secured to the body of the item of furniture or household appliance. At least one securing region for detachably securing the support plate to the body of the item of furniture or household appliance is formed on the support plate and the storage shelf can be secured to the support plate without the use of tools.
