This thesis proposes a space vector modulation algorithm for an asymmetrical six-phase open-end winding permanent magnet synchronous motor（OEWPMSM）supplied by two two-level six-phase voltage source inverters（VSIs）with common mode voltage suppression.Two topologies are investigated.The first topology consists of the dual inverter with separated DC supplies,and the second topology is the dual-inverter fed from a single DC source.A six-phase open-end winding PMSM with open-end windings model is dev...
