Impact of inverter switching pattern on the performance of a direct torque controlled synchronous reluctance motor drive
Paper i proceeding, 2009

The synchronous reluctance motor has gained more attention recently and is a potential candidate to compete with other ac motors. The simple structure and fast torque response make the direct torque control an attractive solution for the synchronous reluctance motor drive system. Different motor, inverter and controller parameters affect the drive system performance in this method. The drive system performance is investigated for four possible inverter switching patterns in terms of the torque ripple, stator current harmonic content and inverter switching frequency in this paper. The results show that switching pattern in which a zero-voltage vector is applied to decrease the torque, regardless of increment or decrement in the flux, has a better performance in the drive system.
