The Open-End Winding Permanent Magnet Synchronous Motor (OEW-PMSM) fed by dual inverters is attracting increased interest in electric vehicle (EV) propulsion systems due to its high power, wide speed range, and strong fault-tolerant capabilities. To harness the outlined benefits, this article presents Direct Torque Control (DTC) for a Dual Three-Level Inverter (DTLI) fed OEW-PMSM drive based on simplified Reduced Carrier Space Vector Modulation (RC-SVM). The proposed DTC-RC-SVM technique for DTLI-fed OEW-PMSM drives features reduced torque ripple, utilizes half the DC link voltage, offers a simplified control strategy, enhances fault tolerance, and increases power capability. The results show that the proposed method provides precise torque control, good steady-state, and high dynamic responses, making it suitable for high-power and critical applications. In order to show effectiveness of this proposed scheme it is compared with existing conventional Three Level Inverter (3LI) fed PMSM drive. A mathematical model of the DTLI-fed OEW-PMSM drive is presented, and the proposed control is tested in a virtual simulation environment using OP4512 for further development in hardware.
