In an Electrical Vehicles (EVs) application, the speed and torque range contribute major requirement to have high-power momentum. The said feature can be accomplished in induction motor drive (IMD) by pole phase modulation (PPM) technique. In the given solution, PPM is employed to 3-phase, 12-pole induction motor (IM), this gives an additional operation mode of 9-phase, 4-pole to IMD. However, during the 3-phase, 12-pole mode, the system had an issue of high torque ripples, this is due to the presence of common mode voltage (CMV) in the inverter. Presence of CMV lead to circulating current in IM. These circulating currents further produce lower order space harmonics in the windings of IM. In this paper a new modified interleaved inverter (MII) topology is proposed to further reduce the CMV when compared to two-level inverter with existing topologies. This reduction in CMV improves the performance of the IM. To analyze the operation of MII topology, a 5HP 3-phase, 12-pole is designed in Ansys. The proposed MII based PPM induction motor is simulated in MATLAB/Simulink environment.
