  • Power converter arrangement and method for its regulation using voltage setpoint values by use of a pre-modulator
    Patent number: 11152868
    Abstract: A method regulates a power converter arrangement that has at least one power converter arm with a series circuit of two-pole switching modules. Each of the switching modules contains a plurality of semiconductor switches and an energy store. At least some of the switching modules are switching modules of a first type and at least some further switching modules are switching modules of a second type. In the method, a voltage setpoint value of a power converter regulator is apportioned into a first and a second setpoint value portion. The switching modules of the first type are driven on the basis of the first setpoint value portion and the switching modules of the second type on the basis of the second setpoint value portion.

  • Arrangement having a coaxial resistor
    Patent number: 10923251
    Abstract: An arrangement has a coaxial resistor. The coaxial resistor is to be placed on an electrically conductive housing, and sensor lines of the coaxial resistor are to be guided through an interior of the coaxial resistor into the interior of the electrically conductive housing and to be connected to an electrical interface in the electrically conductive housing.
