    摘要: The invention relates to a power system that includes an electrical machine 1, e.g., a motor or generator. The electrical machine has a stator 2 with a stator winding connected to a power converter. The power system includes an assembly 6 to reduce, and optionally eliminate, common mode currents between the electrical machine 1 and the power converter. The assembly includes a stator frame 8 connected to ground potential and an electrical insulator (e.g., a plurality of stator mounts 14) located between the stator frame 8 and the stator 2.
