Space vector PWM technique for two-phase inverter-fed single-phase induction motors

In this paper, a space voltage vector pulsewidth modulation (SVPWM) technique for a two-phase inverter is proposed. Such a technique is applicable to single-phase induction motor drives. There are four space voltage vectors and no zero vectors in the two-phase inverter. A reference vector in the square locus is realized by adjusting four space vectors. The switching sequence "two-phase symmetrical modulation" of the two-phase inverter is proposed.
