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

摘要

In this paper the space voltage vector pulsewidth modulation(SVPWM) technique for two-phase inverter is proposed. Such technique is applicable to the single-phase induction motor drives. There are four space voltage vectors and no zero vectors inthe 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 two-phase inverter is proposed.
