Abstract: This paper deals with multi-level neutral-point-clamped inverter (NPCI) driven PMSM high-speed electric drive. Nowadays for medium and high power applications, multilevel inverter technology is more used in high-speed electric drive applications because it offers quality performance. One of the current methods used for constant speed and torque is field oriented control (FOC) in permanent magnet synchronous motor (PMSM). This paper describes the multilevel inverter-driven PMSM drive with carrier-based space vector modulation (CBSVM) strategy in a MATLAB environment with reduced total harmonic distortion and torque ripple. The simulation results are based on inverter output and motor parameters such as stator and rotor current, torque and speed of PMSM. The proposed FOC-NPCI-based PMSM drive is found suitable due to better speed and torque response and less torque ripple. The hardware and simulation results match the effectiveness of the drive.
