The interest in predictive control approach and multiphase drives has been steadily growing during the last decade. Predictive control techniques have been recently introduced as a viable alternative to conventional PI controllers with carrier-based or space vector PWM techniques in the current regulation of multiphase power converters and drives. The developed schemes have demonstrated a good performance...
Multiphase electric drives have been recently proposed for applications where the highest overall system reliability, combined with a reduction in the total power per phase, are required. Strategies like Field Oriented Control (FOC) and Direct Torque Control (DTC) have been traditionally used in these high performance applications. In this paper, a Predictive Torque Control (PTC) method is introduced...
Open-end winding variable speed drives with dual-inverter supply have been extensively investigated for various applications, including series hybrid powertrains and propulsion motors. The existing body of work is restricted to the three-phase electric machinery. This paper looks at the possibility of using machines with higher phase numbers in an open-end winding configuration with dual multiphase...
Numerous space vector PWM techniques have been developed in recent time for asymmetrical six-phase induction motor drives. These are in principle based on either 12 or on 24 sectors in the α-β plane. This paper introduces a modified continuous PWM technique, which is based on 12 sectors and which reduces the switching frequency when compared to the existing 12-sector based continuous space vector...
