Abstract
An electric machine has a multiplicity of windings having a first terminal and a second terminal. At least one node exists to which one of the two terminals of a respective winding from the multiplicity of windings is electrically connected. The corresponding other terminal of a respective winding from the multiplicity of windings is electrically connected to a phase terminal, and to a modular multilevel converter that has a multiplicity of individual modules that are connected up in series to form a ring. At least one tap can be arranged between two respective adjacent individual modules and provides a phase terminal to which the first or the second terminal of a winding from the multiplicity of windings of the electric machine is electrically connected. A number of taps of the modular multilevel converter corresponds exactly to a number of windings from the multiplicity of windings of the electric machine.
