| Sumario: | Purpose. This paper presents a d-q model of six-phase induction machine supplied by a two identical voltage source inverters suitable for analysis the dynamic steady under balanced operating condition. In the analytical model, the effects of common mutual leakage inductance between the dual stator have been included. The model has been developed in general reference frame taking into account of 0°, 30° and 60° displacements between two stator winding sets. The main purpose of this work is to conduct a quantitative study to show the advantage of supplying the six-phase induction machine by a multilevel inverter. The voltage and current total harmonic distortion and the torque ripple rate are the main targets. This paper is organized into four sections. After the introduction, the second section includes development of mathematical models concerning the six-phase induction machine. The third presents the effect of displacements of 0°, 30 ° and 60 ° between two stator-winding sets, and a comparison of three cases. After that, we present a comparative study between two, three, five and seven inverter levels when feeding the six-phase induction machine. For this purpose, simulations were carried out to obtain phase currents and torque ripple rates in steady state. |
