Abstract: In this paper, the mathematical model in Park reference frame of the dual open-end stator winding salient-pole permanent magnet synchronous machine is described. The proposed machine is supplied by its four voltage source inverters based on PWM technique. Then, the feeding of this machine by four two-level cascaded inverters is presented. A multilevel PWM strategy is carried out to control the cascaded inverters. The simulation analyses using the THD voltage, THD stator current and the torque undulation are presented and show the benefits for the proposed machine.
