A Hybrid Multilevel Inverter Scheme for Nine-Phase PPMIM Drive by Using Three-Phase Five-Leg Inverters
Reddy, B. Prathap; Meraj, Mohammad; Iqbal, Atif; Keerthipati, Sivakumar; Bhaskar, Mahajan Sagar ( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)In pole-phase modulation, the phase order is coming down by pole ratio times in high pole mode, which results in the higher magnitude of spatial harmonics as well as higher torque ripple. In this article, the available ... -
A Single DC Source-Based Three-Level Inverter Topology for a Four-Pole Open-End Winding Nine-Phase PPMIM Drives
Reddy, B. Prathap; Meraj, Mohammad; Iqbal, Atif; Keerthipati, Sivakumar; Al-Hitmi, Mohammed ( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)This article proposes a three-level inverter topology for nine-phase pole phase-modulated induction motor (PPMIM) drives by using the two identical voltage profile coils (IVPC) of a four-pole stator winding. In general, ... -
