Abstract
Connection of two 2-level inverters at the two ends of an open end winding induction motor with equal DC-link voltages is equivalent to a conventional 3- level inverter. Better fault tolerance and flexibility in controlling is obtained in open-end winding machine configuration when compared with a conventional three-phase neutral connected electric motor. An alternatingcommon mode voltage (CMV) is generated at the motor terminals because an output from the inverters is given to the motor is not a pure sinusoidal. This CMV result in the production of common mode current (CMC) which causes many problems in the inverter driven motor system. So in order to reduce this CMV a new technique called carrier phase shift (CPS) technique is proposed. By using this CPS strategy the CMV is reduced 50% by just shifting the carrier waves and without using any additional equipment. The proposed topology is verified in MATLAB Simulink.
