“…The rotor is identical to that of a three-phase squirrel cage induction machine. Depending on the control strategy, the DSIM can be considered as an asymmetrical six-phase machine, and therefore the Park model is obtained by applying an appropriate transformation matrix which leads to three sub-models completely decoupled [2], [10]. In this paper the DSIM is considered as the combination of two three-phase machines sharing the same magnetic circuit and the usual Park transformation is applied for each threephase set [11].…”

This paper deals with the energy efficiency improvement of an electrical drive which can be used both in wind energy conversion or motor drive applications. A power factor (PF) control scheme is presented allowing energy efficiency enhancement and optimization in high power variable-speed drives based on multiphase machines. Thus, the double-star induction machine is taken, as an example of multiphase machines, to introduce the principle of the study presented in this paper. In fact, the purpose of this paper is to maintain the PF of the power-winding, of the double star induction machine, in vicinity of unity whatever the drive operating point. Also, this control scheme can be generalized for several kinds of multiphase machines. Keywords-Double fed induction machine; energy efficiency; multiphase machine; power factor control (PFC).I.
