winding based PMSG and two cascaded two-level converter is built in which the vector control position
，
sensorless control space vector modulation are investigated． By analyzing the mathematic model of the
，
open winding PMSG the vector control strategy based on the rotor flux orientation and the sensorless op-
，
eration technique based on the back electromotive force estimation was implemented and then the target
vector assignment method and the corresponding space vector modulation strategy for the two generator-
side converter were also studied． The analysis results indicate that the proposed open winding PMSG sys-
，
tem can not only decrease the generator-side converter capacity but achieve the three-level modulation
effect． The correctness and availability of the proposed system and control strategy are validated by the
experimental results．
