Abstract
A novel control scheme of direct flux space vector modulation (DFSVM) is proposed for inverter-fed AC motor drives. The proposed scheme is characterised by reduced switching losses for the device and low harmonic current at high output voltage for the motor, resulting in a low harmonic loss and reduced torque ripple drive. Theoretical analyses are presented, and the claimed benefits are verified by experimental results
