An arrangement for electric power conversion and an electric drive comprises a power converter that includes three legs, an electric motor including three open-end stator windings respectively having first and second ends, and a power switch. The first ends of the stator windings are coupled to respective legs of the three legs of the power converter, and the second ends of the stator windings are coupled together and have a same electric potential. The power switch is configured to selectively disconnect one of the second ends of the stator windings from all other second ends to establish at most two distinct electric potentials. The at most two distinct electric potentials are coupled to respective legs of a power grid interface coupled to the arrangement.
