摘要：
This paper presents an inverter/motor drive topology and control strategy, which serves to virtually eliminate common mode voltage in addition to reducing torque pulsations existing in typical three phase motor drives. The topology includes a six pole inverter, each pole having half the current rating of the equivalent three-phase inverter, to control a six phase machine. The proposed drive can be implemented with only a slight modification to existing equipment. A new space vector modulation strategy is presented, which allows open loop voltage control and elimination of the common mode voltage produced by the inverter.
