Abstract
An intermediate voltage circuit current converter having two current converter sections arranged in series on the direct voltage side is disclosed. The current converter section has a capacitor connected in parallel with two bridge modules that are connected in series with each other. The output of the current converter section is located on the series connection between the two bridge modules and the outputs of the two current converter sections are connected to a further bridge module. Each bridge modules comprises a series connection of two power semiconductor units. The intermediate potentials on the connection between the two power semiconductor units in each of the bridge modules are electrically connected to one another by a further capacitor, and the intermediate potential of the further bridge module provides the phase connection of the intermediate voltage circuit current converter for a given phase of the intermediate voltage circuit current converter.
