Abstract

In this paper, the advantages of both octadecagonal space vector pulse width modulation (SVPWM) and hexagonal SVPWM are explored for a pole-phase modulation (PPM) induction machine (IM) drive applications. In the proposed scheme, a hexagonal SVPWM is used in the low-speed region and octadecagonal SVPWM is used during high-speed region to achieve better performance over the entire speed range. With this proposed operation, the linear modulation region is enhanced by 9.15% as compared to conventional 3-phase SVPWM in the high-speed region. The basic two-level 9-leg inverter is used to excite the 9-phase PPM IM. The FEM model of the PPM IM and inverter structure is simulated using Ansys Maxwell-2D and Simplorer environment respectively. The proposed method is verified experimentally on the prototype model of 5-hp 9-phase IM.
