Research output: Contribution to journalArticlepeer-review


This paper presents a sinusoidal pulsewidth modulation (SPWM) method with multimode control technique which is particularly suitable for the 3-phase AC induction motor inverter drive. The operational principle of the sinusoidal PWM method based on the flux-linkage vector locus has been explained. With the proposed multimode control strategy, the output fundamental can be controlled smoothly in full operation frequency range. Experimental results have been obtained from a laboratory prototype to verify the effectiveness of the proposed method.
