Discontinuous SVPWM Techniques for Double Star Induction Motor Drive Control

In this paper, we present SVPWM control techniques suitable for a double-star induction motor drive (DSIM). The induction machine has two sets of three-phase stator windings spatially shifted by 30 electrical degrees. Each set of three-phase stator windings is fed by a three-phase inverter. Continuous and discontinuous space vector PWM techniques are presented. Implementation on a DSP controller board is achieved and experimental results on a 15 RW DSIM prototype machine are carried out
