In this work, a comparative analysis between the different performances of stator windings structures for salient-pole synchronous machine with dampers where each structure is supplied by voltage source inverters is presented. In this comparison, the proposed structures which are the open-end stator windings synchronous machines improve the total harmonic distortion (THD) of the voltage, THD stator current and offer best quality of the torque for the high-power applications. Furthermore, the dual open-end winding synchronous machine ensures the power segmentation to increase the freedom degrees of drive system in degraded mode. Indeed, this machine is fed by four voltage source inverters where the dimensioning of inverters is reduced to a quarter power of the machine.
