In this paper, the space-vector pulsewidth modulation (SVPWM) technique for two-phase inverters is proposed. The proposed SVPWM technique is applicable to the two-phase induction motor drives. The two-phase inverters using the proposed SVPWM technique can generate only four space voltage vectors, but cannot generate zero vectors. A reference voltage vector located in the square locus is realize...

The discontinuous space vector pulse-width modulation (DSVPWM) is a well-known technique offering lower switching losses than continuous SVPWM. At the same, average switching frequency, or a switching frequency 1.5 times higher than utilized in continuous SVPWM, the discontinuous SVPWM results in lower current harmonic distortions than that obtained in continuous SVPWM at high modulation indice...
